I suppose it depends how you define "wealth." And what is wealth worth if it's in the hands of a small minority, while the rest go without, for instance, healthcare or a decent education? Even if you are in that small minority, is that the society you want? BTW, the only country I can think of that actually practices laissez-faire capitalism is Somalia: they really have no regulation. Not so much wealth being produced there.
