I didn't say that there shouldn't be demands. Only that there needn't be hyperbole to justify those demands. It just undercuts the argument. Arguments that are grounded in reality are more effective. The idea that we're all going to be working 60 hour weeks with no overtime and no minimum wage and child labor (as the post suggested) without unions isn't grounded in reality. Stagnation of wages without unions is reality.
This is why Trump will end up being reelected. Everyone is doubling down on their positions because no one is using rational, reality-based arguments and are, instead, further entrenching themselves in their positions on both sides.
