Yeah, biggest problem with higher hourly but less hours is the fact that most people are putting close to 50% of their income towards housing. Any reduction in that gross amount will inevitably cut into your disposable (if you even have any) income.

The real solution to this is an abolition of rents and a reduction in working hours, but maintaining precarity in the working class is a function of marketized housing. It's meant to prevent people from staying in one place long enough to form a community and connect with the workers around them. We're at a stage of capitalism where alienation is the primary product of the system and any attempt to resist that is beaten out of us because an end to alienation is by definition an end to the capitalist mode of production.
