I'm not opposed to this. But parents are just part of the rat race often to work until they can't to support the family. How many stories have you heard men joining the military to support their gf, wife and children? (Benefits are super good) whereas the public sectors have miniscule pay, and benefits unless you work at some top 300 forbes job. A person that cut hair or one that bakes bread should be able to save regardless of their job but inflation makes it impossible.

I think there are a lot of contributing factors, not least of which is corporate greed. Shareholders demand ever-larger margins and ever-increasing growth, which leads companies to try to extract more value out of fewer employees for less money.
In a just economy, not every job would be able to support an entire household, but most jobs would, and stability, rather than growth, would be the primary corporate priority.
