As others have said, the problem isn't wages, rich are rich because of returns, dividends and other stuff that, depending on the country or city, is tax exempt, precisely to avoid paying anything. A cynical asshole might even go so far as to say that it creates jobs for lawyers and accountants, which is technically true. It's a win-win-lose for the rich-those ethically wrong workers-everyone else.

Unless the UN or really big blocks like the EU+BRICS start pressing every tax haven to stop pretending that they're doing nothing wrong (which, let's be honest, won't happen, ever), the rich will just move around. They have that luxury, thanks to effectively infinite money.
