Why did the communist experiment, which was committed to equality, abundance, and a humane socialism, generate such oppressive, brutal, and totalitarian regimes and failed economies?

The communist experiment failed, because Communism is based on the uprooting, control and destruction of basic human rights and relationships. Marx makes it very clear that part of the Communist agenda is the breakup, forcible or otherwise, of the family. It is also based squarely on subverting the basic right of personal property, from which all other property rights are derived.Communism bases itself on fundamental lies and moral abuses and the abrogation of very basic human relationships and rights. Theft, home invasion, lying, torture, starvation, and historical revisionism are all hard wired into Communism.

this is a good question! i'll do some research and come back when i have the answer!

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
