Costs are all relative to the place where you live, if 40 years ago politicians in America did not allow the corporate owners to move their corporations to exploit cheap labor of foreign countries, the costs of products would be relative to the wages of the workers where those products are produced.

To clarify, I am not a nationalist, I would prefer to live in a world where we all use one global currency and there are no borders, that way there would be no trade/currency wars and no exploitation of workers in countries where there is cheap labor.
