Economics

Men did not make the earth. ... It is the value of the improvements only, and not the earth itself, that is individual property. ... Every proprietor owes to the community a ground rent for the land which he holds.

Capitalism is the exploitation of man by man; Communism is the exact opposite.

Economics is a subject that really relates to core aspects of human well-being, and there’s a methodology for thinking about these things. This was a very appealing combination to me. Market systems are capable of massive breakdowns that can result in long, devastating periods of high unemployment. And I felt that economists had really learned something about how to address that.
