It doesn’t really seem too sustainable to have to be so expensive if you actually want people to have kids, especially when the US is so famously allergic to the very notion of social safety nets. Median household income in my county is just under $50,000/year, so lets call it $50,000 to make things easy. Median rent for a one bedroom apartment is $1,588/month, so housing alone leaves you with $30,944. Average cost of child care for my city is $16,250/year for kids 2 or younger, so now we’re down to $14,694 to cover all other expenses for the rest of the year for our average household, ignoring the fact that we ignored taxes on that $50,000 income to begin with. That’s $282.58/week to feed a potential family of 3, clothe them, pay utilities, etc. which isn’t a whole lot.
