Any good communist or socialist should, in my not-in-the-slightest-bit-humble opinion, have a good basic understanding of capitalist economics. We must, of course, know the enemy, but slso the capitalists really are running the world, and reality
does bite back. There are huge theological distortions in capitalist economics — capitalist economists are as much propagandists justifying the position of the ruling class as they are scientists — but they do need to keep a global economy running and they cannot retreat into pure fantasy even as far as religions. (And even religions have to have some connection to the realities of human psychology to retain believers.) Always keeping a sharp eye out for theological distortions (which we can do not on an ideological but on a
scientific basis), we can still learn much about human economic behavior from capitalist economists, especially the relatively liberal capitalist economists.
