Not even an amateur economist, but intuitively, it feels like there is a very delicate balance needed in taxation. Higher taxation (likely Eurozone) is needed to support the poorer sections of the society. However too high, it kills innovation and growth and in turn the whole pie size. Too little taxation (likely US), pumps innovation and growth but destroys support for poor but also hinders investments in infrastructure needed for these innovations to thrive. I'm not going to comment on the correct levels, as I have no clue, but one thing that feels certainly wrong is complexity of taxation. This gets exploited by a small percentage of people while leaves a large percentage afraid to venture.
