How, for instance, could companies like DSG - the UK's largest electrical goods retailer, make a profit without cheap far Eastern labour, and it's only cheap because they're poor.
Economics 101: A company's profit is the product of two factors: The number of items sold and the profit margin on each item.
Let's imagine that the far East was far richer than it is now. For DSG, this means labour costs go up. But it also means that they have millions of extra people who can now afford to buy DSG products. The increased cost narrows the profit margin per item, but they're selling more items. So it's more or less a wash, even before you take into consideration the economies of scale that reduce per-item costs as total output increases.
At the same time, we have the added blessings of increased wealth in the world: more people can afford to educate their kids, so there are more thinkers, more scientists, more inventors. Consequently, we get better and more efficient ways of doing things, which in turn help to create more wealth.
To think that keeping the poor poor is in the best interests of the rich is to succumb to extremely short-term thinking. A rising tide floats all boats.
So DSG would love a richer far East. But that wealth won't just appear overnight. It has to be created, and the only way that's going to happen is by companies like DSG continuing to do business, transferring money paid by customers in Britain to workers in the far East. And if a Malaysian worker is paid half what a British worker is, then good: hire two of them, feeding two families rather than just one, and getting twice the output in return. How can that be thought to be immoral?
