Yeah, but it's one of the few economic systems that won't collapse inward due to inherent flaws that can't be fixed without removing its core principles. Capitalism is focused around trade and fair commerce. Its major flaws (such as corruption) are related to the people, not the idea itself, because the basic idea behind capitalism is so broad, its principles can be applied to any place that operates even vaguely similar to America or other capitalist countries. Communism, meanwhile, relies on everyone working together and not expecting compensation for doing more than they usually do because someone else can't handle their workload due to, say, injury.
