If you want more children you have to reward mothers directly and significantly in line with their potential earnings. Not a paltry few thousand dollars, but more than enough to offset the price of daycare in hcol cities. I want to mimic social security but for families, and that means concentrated benefits (that directly incentivize voting turnout and interest group formation).
At the same time I want our country to continue to be competitive globally when it comes to business, and not turn into whatever Europe has become. We can't just add this as a line item to our budget. We are not that rich and we have financial problems that are looming.
