Modernity has also made life really fucking complicated. A 16 year old could walk to the factory, get some paper money and then do what they wanted with it.
Nowadays lets say your 16 year old wants a car and a job. To do that they need to schedule multiple tests with DMV, lessons with a driving instructor, update insurance documents and find the time to do hours of practice with you. At the end of that they need to navigate buying a used/new vehicle and setting up insurance. Then they need to navigate the world of job applications, and if they manage to get hired they will need to have their direct deposit bank account setup and have some kind of credit card payment system setup so they can use the money.
Seriously just typing this I get exhausted. It makes sense why parents are hovering over their kids because there are 10,000 things that need to get handled just to like be a "person". You can either watch your kid drown in a mire of bureaucracy or just let them focus on school and offload all of it from them.
That's true, but the parenting part isn't actually that complicated, particularly at a young age when you're laying the foundation. Basically just stay out of the way and let your kids do stuff. Don't do anything for them that they can do for themselves. That way they learn problem solving skills and gain the confidence to follow through on things, so when they're 16 they are capable of navigating buying a car and getting a job.
Somehow this isn't intuitive for parents, though. They feel like they need to show and do things for their kid, rather than letting them pick up the experience of doing themselves.
When I was growing up my parents were borderline neglectful in how they handled my brother and I, but in that neglect we were forced to deal with situations ourselves, gain experience, and discover who we were. Counterintuitively, that approach was actually more fruitful than being over-present.
Are your kids fully grown adults yet?
