Woman are only interested in marrying the top 20% of men, the other 80% will either never have children or they will live in an unhappy marriage and then get divorced raped, they'd be better off paying for escorts.

The median 25 year old Chad is earning about 55,000/year after tax
If chad acquires four 18 year old wives with three of them working 40 hours a week their total household income will be atleast 136k after tax

One of the wives will be designated as a stay at home mother.
A 5 bedroom home could be paid off in 3-4 years. You can impregnate each wife 3 times over 5 years and your wives can transition to part time work in that time, four bedrooms for 12 children should suffice for atleast 10 years by then you should be able to afford 1 or 2 more houses to give the older children some space.

Tl;Dr chad can easily afford to impregnate 4 women 3 times each, women don't have to settle, they can share chad and be better off financially

I want to have 10 children with a fembot.

what if you have dedicated au pair and tutors for all the children

White Americans all have cheap 12 room mc mansions and earn the highest incomes in the world but most still won't have kids
