We can't get rid of slavery, the economy will collapse!
We can't get rid of child labor, the economy will collapse!
We can't have 8 hour work days, the economy will collapse.
What? The workers want TWO days off a week? Don't they know the economy will collapse?
basically if a capitalist says the economy will collapse because of a reform that will help workers, you don't need to believe them, also it's gonna collapse anyway, that's what it does under capitalism.
