A standard IKEA Billy bookcase (80cm wide, 202cm high, white) costs $59.99 in the United States. The same bookcase sells in Germany for €38.00, that's $52.82.
The IKEA bookcase factory in Danville, Virginia pays its workers $8 per hour and has rather horrible anti-union worker policies. The IKEA bookcase factory in Sweden pays $19 an hour which come with quite likable union controlled worker policies.
A spokesperson of the IKEA subsidiary Swedwood offers this explanation:
"That is related to the standard of living and general conditions in the different countries"
That statement is correct. With lower wages and higher prices the median U.S. standard of living is now below the western European one. One wonders if/when this will get acknowledged.
