> 2. Boomers, GenX, and Millennials were culturally trained to a 2 child policy for environmentalism.

I’ve never met someone in real life who’s restricted how many kids they want for environmental reasons.

It’s always always for practical reasons - money, space, time, effort, and interest. What lifestyle do you want to live, and what are you willing to sacrifice.

I think culturally parents have shifted to spending more resources on each child, so having more children is infeasible.
