Of course, the top of that chart needs to be revised pretty extensively as well. Agricultural policy in the US, Europe, and elsewhere is about as remote from laissez-faire capitalism as can be. Price supports, government-sponsored research, tariffs, safety and health regulations, laws prohibiting or allowing unions (for example, in the US, farmworkers are not covered by the National Labor Relations Act, although there is an agricultural version in California specifically), etc. Still, a very amusing comic.
