There's not doubt Americans are under educated when it come to understanding just what socialism / marxism is and how it fails time and time again, but not before millions die, economies ruined. On paper it sound good to those disenchanted with their place in life, they've been told they are victims. They are the easiest to indoctrinate along with the young, that do not question those who would teach them socialism / communism.
It never ever works out good for the people.
It the very reason people see America risk their lives to get in.
