Oh I agree completely about income inequality, it's a serious problem. I don't think taxation is the solution though, at least not straightforwardly. The problem isn't so much not enough taxing people, it's taxing the wrong things and giving ta breaks to encourage rent seeking behaviour. So we should seriously look at land value taxes for example, but that doesn't necessarily mean increasing overall taxation. The tick is getting the balance right so you're not distorting your economy.
