It'd be nice to see an example of a socialist county that hadn't been constantly attacked and sabotaged by capitalist countries and allowed to go its own way. Then at least we'd be able to do a fairer comparison.
You mean like what the U.S. did to Central American countries during the 80s? OR Vietnam, where we overthrew a democratically elected socialist government and installed a puppet, then dropped napalm on them when the didn't like that?
Where this falls down is that there were other capitalist countries that didn't do the bad things you describe. I challenge you to name a single experiment in communism that didn't lead to worse outcomes.
