1. more competition in the job market leads to higher male unemployment and lower wages for all

On top of that, it doubles the household income which doubles the cost of living. Things like houses and cars are priced based on what people/families can afford to pay for them. Therefore, when household income goes up, so does housing costs and everything else. So at the end of the day, families aren't actually improving their quality of life. They're at the same station their parents/grandparents were at, except they're both having to work, where previous generations managed to maintain that station and relative quality of life with only one parent working, and the other raising the kids.

The kids are the ones who are getting the shaft in this equation. And the consequences of the wholesale abandonment of an entire generation of children is starting to manifest (see above video).

This may be the thing that brings about our downfall - the wholesale abandonment of the children to "daycare". I'm not sure if such a thing has ever been seen in human history before. Nobody knows what to expect. But I think it's already turning out worse than anyone imagined (again, see above video).
