"Now ask those same factory workers if they would prefer the current system or one where they can organize for greater benefits and standards of living. If it was good enough for us, after all, it is good enough for them."
And ask them if when they do that, the company will just move to someplace where they don't have to deal with unions and thus they would lose their jobs. Union are a very bad Marxist idea. They are causing every company that uses them to go broke and the unions and their leaders are always corrupt. They are not needed.
I wouldn't go that far. Unions in the past have stopped some serious abuses of the workers. And there is the Solidarity union of Poland that helped end communism in Europe.
