They haven’t lived under real communism. Wait until they can’t drive a car, use their cell phones, watch a movie, watch tv, talk on the phone, go to the mall, be with their friends.
Wait until they have to march together, live together, no real school, not enough to eat and no heat, a/c etc.
And wait until they are told what to do 24 hours a day. I mean they can’t walk up leave the room.
