I assert that the economy is a zero-sum game with winners and losers. You laugh at my naivete, but you'll have to laugh at the theories of a lot of leftist economists, too. Marx has a complex explanation in which he shows that value comes from extracting more labor from a worker than the worker is actually paid for. Marx's theory is only one of a few generated by economists, but it seems to me as valid as any. If that theory is correct, then capitalism can't just be creating wealth out of thin air.
Capitalists extract their monies, ultimately, from the labor process.
As for your view that it's better to have five million affluent families than one million, we are still talking about incremental unequal distributions of wealth. The four million families added to the rich list is even more grotesque when we consider that the real earning power of the lower stratum of society has gone down in the past 20 years, not up. Your aim is to celebrate the new aristocracy and hope it will give alms to the same old poor folks. And we need to note further that all your solutions to poverty and inequality have to do with personal arrangements, charity, and the like. But we know historically that this trickle-down generosity only assuages the consciences of the rich without making serious structural changes to a system that has to rely on cheap labor.
