Anyone looking for a challenging read should consider Milton Friedman's book "Capitalism and Freedom". It's short, but very dense. He covers topics like a negative income tax (which you've heard of) and ideas you've probably never considered (like school vouchers, elimination of occupational licensure, and elimination of tariffs). The downside is, if you find his arguments convincing, it will leave you feeling even more angry about the current role of government in society.
