Behind the discussions about the future of Social Security, the situation of the Trust Fund, the requirement for personal retirement accounts and other such financial instruments, you have some basic reality-based facts that are sometimes forgotten.
Below (the fold) is a simplified description of the social security problems that we face and how not to solve them – in non-financial terms.
Imagine the USA as a big family; with no interaction with the outside world (we’ll get to that part later): you have 1 senior citizen, 4 working age people, and 1 kid.
The working age citizens provide all the goods and services needed by everybody:
– 1 provides the basic stuff – food, housing, etc ; let’s call him/her the construction sector
– 1 takes care of Senior and Junior; let’s call him/her the nurse/teacher
– 2 crank out TVs for everybody’s leisure and entertainement; let’s call them the TV guys and let’s say that they produce 3 TVs each (one per person)
The first important thing to note in this model is that at all times, this group is self-sustaining: all the work needed at any time is done at that moment by someone within the group, and all work done is consumed by someone.
The other important thing to note is that 4 people work to provide for the needs of 6 people. In effect, one third of their work is taken from them at any time to provide for the needs of the non-workers, i.e. Junior and Senior.
In the real world, the same thing happens on a larger scale, and these transfers can take 3 main forms:
– intra-family transfers: you feed your kids, pay for their education, your parents live with you, etc…
– government: you pay taxes and the government either spends it (schools) or redistributes it (social security)
– financial instruments: people can save, or spend their savings (via bonds and shares). Saving means that you store your work for future use. In practice, bonds and shares are a “tax” on your current work: a portion of your work is used to pay off debt or to pay dividends to shareholders. This is still you working and someone else (Senior, usually) enjoying the fruits of that work. “Dividends” sound better, but they still are really a tax on your work.
In any case, whatever form the transfers take, they should not hide that basic fact: 4 people work and 6 people live off that work.
Now take our family 50 years from now. It is now composed of 7 people: 2 seniors, 4 working age people, and 1 kid. 4 people working, 3 not, but all still with needs.
What happens now?
The construction guy still does that. With a little bit of effort, he is still able to make all that’s needed for 7 people instead of 6
1 and a half workers are now needed to take care of junior and the 2 seniors (there is little room for productivity improvements there) which leaves:
1 and a half workers to crank out TVs. If there has been no improvement, that’s only 4.5 TVs for 7 people. In order to have 1 TV per person, you would need each worker to be able to make 4.66 TVs instead of 3. Over 50 years, that does not sound impossible.
So, if you forget about productivity improvements, this is why you have the cries about social security crisis: either you have fewer TVs, or you find a better way to make more, or you will take less good care of seniors and junior. What should be done?
– the simplest (and pretty realistic) solution is to say that TV production has made such progress that 1,5 workers crank out as much (or more) stuff than 2 guys used to, so there are enough TVs for everybody and there is NO crisis. A larger portion of work goes into caring for the dependents (42% now instead of 33%), but that only reflects changing needs;
– if productivity increases are not enough, you can either take less good care of the dependents (only 1 worker to take care of the 3) and keep on cranking out TVs as you used to (2 workers), or you can decide to take care of your family and reduce your consumption of TVs. A slight variation is to say that you save up one TV today, mothball it and use it in 2050. in that case, you have 5 TVs for 6 people now and 5.5 for 7 in 2050 which might after all be sufficient in both cases.
To get back to the social security debate, the first item is hoping the growth will be strong enough to solve the funding requirements of social security, while the second item amounts to solving the problem by either reducing SS payouts or increasing payroll taxes.
It does not change the fact that 4 people are working to fulfill the needs of 7 people. If you expect to give only one third of your work for the non-workers, they will live less well, relatively. If you give 42%, they will live as they expected to, but you will be relatively worse off. This is the unavoidable reality of an aging population – if less people work, either they are taken care of by those that do, who then have less for themselves, or they are not taken care of (or any combination in between, of course)
Now bring in the outside world into our little model. There are two easy ways the outside world can help improve the situation:
– one is immigration. Bring in one more person of working age into the community, and presto, you can crank out again as many TVs in 2050 as you used to without any increase in productivity AND take care of everybody (including the newbie);
– the other is inter-temporal trade through international investment. You give today one of your TVs to foreigners (you have 5 for 6 people) in exchange for 1.5 TVs in 2050. With no increase in productivity, you can take care ofthe dependents as you’d like (1.5 workers) and with your own production (1.5 workers making 4.5 TVs) you end up with 6 TVs for 7 people, close to what you would get now. You make a small reduction in your living standards now to improve your lot later.
As other countries are at earlier stages of development (and have faster growing population), it makes sense to think that they will be able to crank out 1.5 TVs in the future and give them to you as a fair price for having given them 1 TV a while before. in a more realistic sense, you don’t actually give TVs today – you take time to go to other countries to build factories there or to teach them to do it, and get a portion of future production for you as a payment
To keep on consuming as much as you want in the future, you either need to get more workers in the future, or you must save now and invest in a place with more workers. (Getting productivity increase would basically mean that you need to invest in new, smarter ways to build TVs yourself, which means spending some effort now to do that, which will reduce you current TV production in the expectation of increasing your future one – it’s still saving to invest).
As you can see, there are two issues: one is the size of the pie, and the other is the sharing of the pie. The size of the pie depends on productivity growth, which in turn, depends on investment, which in turn depends on saving. Saving means working now and storing up that work for future use. Mothballing a TV is the dumb kind of savings; producing fewer TVs but taking the time to invent new, better ways to make TVs (or teaching others to do it for you) is the smart kind of savings.
The claims of the SS privatisers is that they will make the pie grow faster by unleashing market forces that will be able to make those smart investments. But is this true?
First of all, note that private accounts do not provide additional savings if they come instead of the existing public saving so they will not provide MORE investment. Will it be smarter? Smart will come from the people making investment decisions. If you accept the hypothesis that private investments are smarter than government investments, then you should reduce government spending, not reduce government funding.
As I wrote last week about the falling dollar, the current problem of the USA is that they consume too much and rely on foreign lending for their investments. If the solution is to save more now (especially to invest in other countries in order to have the returns when needed, in a few decades’ time), this government is worsening the problem rather than helping to solve it, by spending like a drunk sailor and increasing the country’s external debt at a time when it should be accumulating foreign assets for future needs.
To get back to our “family” – half the TVs are already being provided by the outside world, and the only reason they are doing it is because the 2 two US “TV workers” are busy – one making guns and shooting them off at or near others, and the other writing IOUs as fast as his hands can do so. Is this sustainable?
(Foreigners might actually welcome SS privatisation, because it will mean that the TV workers will target their guns at their Seniors to get them to work a bit more instead of at them…)
