Surely people going to jail for the wrong reason is something exclusive to the Soviet Union and not to all countries with a legal system? Like, damn, I feel sorry for your boss, but in dire circumstances such as those of the late 30s / early 40s in the USSR, excesses and abuses were sadly made because of the overwhelming conditions.
Your boss may have spent his teens in a gulag, but the fact that he lived to tell you that is because the Soviets managed to miraculously defeat the Nazis and prevent them from genociding the Slavic peoples they categorised as "Untermenschen" according to the infamous "Generalplan Ost", which implied genocide of almost all people between Germany and the Urals. If it wasn't for the Soviets, your former boss would have been murdered in a concentration camp by the nazis.
