One of the most basic problems with capitalism, according to Marx, was:
a) lazy workers who wanted economic equality but weren't responsible enough to handle it
b) greedy capitalists who were unaware of what was going on around them, socially and culturally
c) that it only allowed a few individuals to have power, even though many individuals did the work
d) that it was a stagnant system that refused to allow change in the type and quantity of things produced.
