Just to clarify, capitalism only really succeeds where there is a democratic style of government and all people feel that they have some say in how they're ruled. Freedom of ownership is a cornerstone in a capitalistic economy. Most true monarchies are based on the idea that the monarch owns everything, or could own everything if they so chose.
As I mentioned before, Communism is simply a mask used by oppressors seeking to loot for their own gains by forcing owners to surrender their property to the state. Communism uses a centralized economy - the Communist state owns everything. Capitalism doesn't.
I don't think I've ever heard of an instance of capitalism going bad. In the case of Vietnam, it was a matter of anti-colonial sentiments in a country recovering from a war. Ho Chi Minh just happened to keep his political infrastructure in place while the other politicians were more concerned with the here-and-now rather than looking forward.
