Interesting second order affect:
lack of childcare -> smaller available labor pool -> disproportionate difficulty hiring in childcare (because it doesn't pay well) -> continued lack of childcare
We could actually be looking at a bistable system, in which (because childcare jobs are towards the bottom end of the pay spectrum) you don't get available childcare unless you have surplus labor, and until you have available childcare you will have a labor shortage.
The solution would be the pay more for childcare, but that money has to come from somewhere, and a lot of people who require it cannot pay a lot more. A conundrum...
