Greger may have worked in construction for a long time, but he ended up running a construction business in Florida: Thus little enthusiasm for trade unions. But I do agree with him. Unions benefitted workers by increasing their incomes and security. But there are multiple strata of people below that level in our society. Unions did nothing for them, and made upward mobility more difficult.

Sure, a poor young man could go to trade school and then apprentice into a union. But he had to survive during that training program, and then wait in line behind all the legacies. Being a son of a union member was a great "in".

The $15 minimum wage could actually help those people a lot more.
