To be honest, i'll prefer to be a stay at home wife. But this has slowly become known as a lazy job and that I should entrust the government to education my children so I can earn money for the family.
Many people competing for the same jobs drives wages down. More than half of households are dual-income households.† This increases the labor pool, which drives down prices.
Ironically, it would seem that, if more families switched to one parent being the primary breadwinner, it would drive up the cost of labor and make single-income households a more sustainable proposition for more families.
The knock-on benefits from the additional time and attention the now stay-at-home or part-time working parents could give their children would have a generationally positive impact on well-being and prosperity.

Most children are probably better off having more time with their parents and less time in a government school. The simple reason is that each child gets more individual attention. A parent's ability to teach might cap out around middle or high school, but the educational quality for those early formative years is likely to be as good or better with homeschooling.
Having one parent at home full time, or working part-time, leaves that parent more time to manage the household, which introduces serious efficiencies and savings over time.
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.
