Hmmm.... IMHO economics is a point that should be discussed. Of course not everyone is an economist. The problem is that people decide how the economy should be run (i.e. voting for a welfare state, limited state, etc...). This affects people a hell of a lot (e.g. the financial+current bailout will cost every tax payer $10,000). Large groups of people already made very bad decisions on this topic earlier this century. Good decisions is the difference between S. Korea and Ghana. Astro-physics, the finer points of quantum mechanics or the Hilbert effect do not affect people directly that much.
