Yes Jon...but what is that makes labour cheaper? Think of a self employed man panning for gold in the U.K and a self employed man panning for gold in China. Assuming they are both as proficient as each other, what is the difference between their tools? Answer:ZERO. What is the difference between their Productivity? Answer:ZERO. What is the difference in their costs? Well that is ALL down to taxes and regulations which come from Government. You keep blaming 'labour costs' as if it is some esoteric problem with unknown origins.
Anyone would think that government is the only villain in this scenario. Labour, through its union power, is a terrible thief, along with it's partner, capitalism.
Unions put the wages up---Factories put their prices up. Both of them, in countries lke the US, UK and other major producers in the West, use their governments to sell machinery to poor workers in underdeveloped countries, so that they, in turn produce more and more raw material at cheap prices. Those labourers get more and more into debt while their counterparts---probably socialists, if not communists, get wealthier and wealthier and, actually go on holidays to those countries, just to rub it in.
I don't have any illusions about anybody. We are all as bad as one another and only complain when we are having the bad patch.
