Nonsense. As nations or people become more affluent and wealthier, they have smaller families. Eventually, population will drop. Consider this; there are more people now than ever and waaaaay more mechanical means to do things than ever, yet unemployment isn’t out of control because of that.
Other than certain economic crisis that can affect employment, regulations is a biggies along with minimum wage requirements, mandatory bennies and payroll taxes and insurances. machines are cheaper.
Our country’s population won’t drop as long as we keep importing unskilled, uneducated third world people. Germany says they need those refugees because their population was dropping, now they’re figuring out that most of them are unemployable and want welfare.
Affluence isn’t correlated with family size.
Rich families tend to have more children than the average American family, and this holds throughout the West.
Furthermore, until very recently, increasing affluence had no impact on family size in America.
What did it was a cultural shift that undermined the family & the widespread adoption of birth control (which itself wouldn’t be an issue, if, again, the family wasn’t demonized in favor of hedonistic depravity).
At least, I don’t think it’s that big an issue in the grand scheme of things.
But yes, regulations & taxes are bad news for business in most cases.
