It is literally impossible for everyone to obtain wealth. Wealth isn't a number or physical circumstances. Wealth is having economic power over the people around you. Success is a little more nebulous, but when thought of as a relative of wealth it's similarly contextual.

The danger isn't everyone but you getting wealthy. The danger is that wealth tends towards concentration. And it tends to concentrate around people who are already wealthy. The danger is, bluntly, that things will get worse for all but a few and most people will be so caught up in a red queen's race that they can't see how to stop.
