No, my point is that you're conflating "expensive" with money

Yeah a lot of my points are about money. But it's also free time, responsibility, etc

For example my parents used to drop me off for a friends birthday party and then go away. There would be adults there who they trusted to look out for me, and they could use that time for themselves for a bit to do whatever

Nowadays parents literally stay the entire time. That's a pretty large chunk of time that my parents had to themselves and parents nowadays do not. I don't know what other term than "expensive" to describe that, but it doesn't have anything to do with money
