I upvoted you, but I want to also vocally agree with you because I think it's important. Even if you don't come away agreeing with the conclusions of Marxist economists, etc., understanding it is worth the time it takes. Considering theories that are not automatically in agreement with those that currently run the show is valuable.

(This is why I've read a solid chunk of the Austrians. I generally laugh at them. But I've read their stuff and I can think in it once I get into the mindset.)
