In the US insurance (of all types: car, house, health) is a major expense and only getting worse.
But the two largest costs to our finances are ridiculously outsized: Child Care and Health Care. We pay more for our children and health insurance / care, than our house + cars (+student loans) combined.
These seem like two areas where intervention is not only possible but likely to help just about everyone. And, if those are solved, I wonder if this "fertility crisis" I keep hearing about goes away too.
