The problem with the old communist texts is that what they called capitalism, and what we call capitalism today are two entirely different things. Capitalism back then was just as terrible as they described it. It had large issues, with a very few people making a lot of money, and the rest essentially living as slaves with no rights to speak of and no chance of making it out of poverty.
