Oklahoma is one of the lowest cost of living states in the nation, because it’s a hell hole with no social services and has been already doing Project 2025 for the past five years. This means salaries are similarly depressed - as a teacher, my first year take home pay per month was $2200. If I had a child then I would have nothing between day care and rent. (And I also would have needed the daycare, first year teaching is 60-100 hours a week.)
The people working at the facility are likely barely qualified and probably not making enough to support their families - likely on welfare.
This could be “premium” childcare like a Waldorf school or it could be the cost of putting 2 kids into regular daycare in an expensive city like San Francisco. It would certainly be cheaper in less expensive places, but incomes would also be lower.
