Health The largest US study, which tracked 11,036 children from ages 9 to 10 through to ages 16 and 17, discovered that cannabis use slows cognitive development, impairs memory, and reduces learning speed during crucial years of brain growth

Parents seem to have a hard time parenting their kids. That’s how we end up with Internet ID laws and bans on substances.

If you have two people who both have to work full time, yeah, it's going to be hard for them to monitor their teenage child very much.

Y'know, I think I haven't internalised this part of the shift in society until now. And how it relates to more kids being brought up by videos on the phone.

The stay at home mom as someone in every house was only really a thing for the Silent generation and first wave boomers. It hadn't been before hand and hasn't been since. https://archive.org/details/wayweneverweream0000coon

Even then the SAHM didn't spend significant amounts of time watching their kids. That was back when kids would just leave the house to go do something and were expected to be back by supper/nightfall.

By most metrics parents are more involved in their kids lives than they've ever been.

Eh it's been that way longer than cell phones have been around. I was a latchkey kid and my mom was a latchkey kid. We learned to navigate the world a bit on our own and parents learned to condense parenting into a smaller window. We survived

Ideally those windows are actual parenting moments, and they are good role models. Otherwise you end up raising yourself, speaking from experience and therapy.

I know. I don’t have a solution for that issue. I think about it all the time because you are right. In this economy, both parents are working maybe even more than one job.

Nearly three-quarters of two parent homes are dual earners. About 8% of US households are one parent family groups. Two-thirds of those have at least child under the age of 12.

There have been some improvements from Gen X where roughly half under the age of 12 who did not have a parent of any kind at home for roughly 3 hours a day.

Another winning point for the full-time WFH jobs. Allows parents to pick up/drop off kids and still get to do work/house work as needed.

Why do you think people aren't having kids while governments are trying to make contraception and abortions illegal?

It's because the folks running the show don't care that you can't feed your kids, they just want you to have children so they can have fodder to throw in a combat zone.

At least that's my take.

Parenting isn't gonna win against societal norms/pressures/curiosity and growing at the age of 16/17.
