First, you have about 90% of the births come through at least CA through welfare because the government pays for the births and the care.
The very wealthy can afford it, have 2-3 and care well for them.
The middle like me have one child or so because of limited means. My wife says she knows she will regret it but that we really can't afford another child. To raise another child. To pay triple Obamacare medical rates and so on.
Then we look at others on welfare and they are birthing them like breathing mints and it is all paid for by taxpayers. But IMO the breath mint parents are not all that responsible and don't live by the same common sense as we might.
Something is very wrong when the most responsible are not the ones growing the population IMO.
Have more children. You will figure it out. You find out real quick that you buy a whole lot of worthless crap.
Besides the more you have the cheaper they get to be. They kind of have their own volume discount. You get smarter at raising them as well. And they have built in friends.
