OP mentioned 5 properties and 5 children. Taking your suggested budget as reference today we’re talking close to $1.5-2m just in properties alone. That’s 10-20 times the median wealth per adult in the US while supporting a very large family by today’s standards.
I know many software engineers with similar assets, most done have 5 children but they don’t want them either.
Software engineers now are paid much better than printers were then
