My point is just about anyone can have children. You just have to align your values and lifestyle into a structure that can support them.

The Amish have had a steady birthrate well above the national average since WW2 at 6 to 7 kids per family.

Are they living on welfare checks? Do they have more income than an upper-middle class family that lives in a big US city?

No, they value family, community, and self-reliance above self-worship.

The Amish are a hyperbolic example to prove the point. But, are modern Americans incapable of the same things on a smaller scale? Only if they refuse to sacrifice.
