Marx also lived on the charity of others...he didn’t work, but lived off of his wife and his wife’s family and Engels (who had some money). So Marx did okay...but it is thought that at least one of his children died of malnutrition, because apparently the money was to support him in the lifestyle befitting a hero of the people (including hiring cooks and housekeepers) but not enough for his dependents.
He was a absolute POS, but because he was Jewish, even though he was an atheist and entirely unrepresentative of the Torah or Judaic principles, a fair number of Jewish Americans and pseudo-intellectual academics worship him. Very sad.
