Yes, but only during periods of peace and/or expansion.
Marriage rates fluctuated with the economy then, too, but most problems were local or regional.

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.
