I'm no Marxist. I love competing in the market, and the last thing I'd want is to live under communism. My wife grew up with it in Minsk, Belarus, and I am absolutely, thoroughly convinced of the misery. But if you select the right passages, Marx can be read as being incredibly current.
right after his anecdote about accidentally listening to Das Kapital on the radio (he thought it was a story about a startup)
he loves competing in the market because it has worked out for him, not because it's universally better >_> his dislike for communism, mediated by his vicarious dislike for the Soviet Union, completely neglects 1) the extent to which any instance of Actually Existing Socialism is embedded in a larger world system; and 2) the level of technology present at the time (obviously we live in a very different technological landscape today)
