The "they will work harder" argument is bullshit. If that would apply, companies giving their employees more say and shares would be more successful, and drive away the others, all without the need to form unions.
I mean it is possible that shareholders will work harder. But that is not an argument for unions.
Also, some employees are people like cooks or janitors. Will they really work harder, and what would that even mean? What if they just do their jobs? Does a janitor at Google really deserve more money than a janitor somewhere else? What makes them the "chosen ones"? Just lucky to work for a successful company?
