You do realize that those household income figures are based on single-income families in the 1970s and two-income families in 2005? In other words, just the baseline requires twice the work now as it did then to achieve parity, and it comes at the cost of removing parents from their childrens' lives.
That’s part of why I said "So assuming everything’s equal, which it’s not but there are inequalities favoring both sides,".
I could list several details supporting claims that homes and incomes between now and then make them both more and less expensive than the dry numbers indicate. But for a variety of reasons, respectfully, I don’t think discussions between people with their minds made up, heals dug in and ignoring counter evidence accomplishes much.
Life’s short. Best regards.
