Don't worry. We already have this in England. We cannot consider having another child because it cripples us financially.
We pay $1141 per month for childcare for our little Bathsheba-Anamalech (good Biblical name).
We cannot possibly think of paying $2000 per month for another child. Even when she goes to school the pre and after school costs are harsh, but we could afford to have another then. But with the growing cost of living in the UK (gas prices have gone up by 66% in 2 years - and everything else seems to go up way above inflation) it is getting harder for average earners to cope.
But if you are on welfare you can pop them out one after another and the government will foot the bill. A lone-parent household raising two children on welfare costs the public purse more than $19300 a year in benefits alone. Britain is the lone parent capital of the world with 3.2 million children raised in single parent households. Now many of those will work, but I am talking about the huge Chav population of undereducated (sound a bit like Uncle Al here but call it as it is) school children who have children at 16 and their children will have children at 14 etc. They will never work because they don't have to and for every extra child they have, the better off they will be.
Most working couples or lone parents I know have just one child these days.
BTW my daughters real name is Natasha , just joking about the Biblical name
