To be fair, you can also get a nanny for about that (going rate is $20/hr or so) which works out with two kids.
Still though, my point is that high costs of child care in the city are a wedge that furthers the gap between rich and everyone else.
Is this true? When I was a kid my daycare was like 30 kids per teacher. It was called "Mother's Day Out". I can't remember the cost but judging by the amount of time I spent there it was basically free.
Fundamentally, it is a business that does not scale, as you need a set number of providers per n children, and low values for n are probably going to be associated as better value. There's really no way to get efficiencies or scale, as the personal interaction and attention is what parents are really paying for.
So it come down to a question of local real estate prices and prevailing wages for the area, so I'm assuming mindvirus lives in a city with a very high cost of living and real estate costs.
Comparing just dollar value of services is not of much use across countries.
It's like saying, interest rate in India is 6% while in US it's 1% why Americans are not putting their money in India. The info you are missing is inflation.
5k is not a lot in mega US cities and these guys will not move to some cheap city because they'll not find a job that pays that well and gives them ability to support such a high quality of life in smaller/cheaper cities.
Unsurprising, because only king would be earning this kind of income per month.
