I don't think anyone wants suffering, but solutions are never as simple as they appear to be when poverty is involved.

Unions have a few positives, but, especially in the US, unions have a reputation for historically becoming corrupted by organized crime, strangling businesses into oblivion, and/or making it impossible for companies to fire incompetent/lazy workers. I know it's not like that in some places in Europe, but the US has been burned by truly egregious unions that have set back progress for decades.
In fact, both wages and life expectancy were improving faster before labor laws came into effect.
Honestly, I don't really see how people cannot see it as anything other than exploitation of human life. Maybe homeless people exist so it's less obvious and is why the government has never done anything to make that go away.
