A few of Socialism's/Communism's greatest hits:
Gulags and forced labor camps, mass starvation and food rationing, "reeducation" torture agencies, forced abortions, forced relocations, no free press, no freedom of movement (travel), strong borders (to keep everyone in), mass surveillance and data collection by government agencies, and hyper control of every aspect of life: where you live (house or apartment, city or rural), how much and what you eat, how many children you have, what kind of car you drive (if you get one), when and how many can gather together in a single place (permits for all gatherings), and so much more!
With all of it's faults, I'll still take Capitalism...
