Why did you have to be a 24/7 presence for your kids? Your parents let you roam everywhere and that worked fine? Don't trust the news and their endless doom scrolling... The world is far safer now than what you were raised in.
Anyone could choose to do their own very small business, even just being a handyman, and have your kids go with you.
The only thing kids actually require is food, water, and shelter. Everyone in the modern world can do that. Kids don't need helicopter parents or endless driving around to activities or money being spent on college. I would argue college is a net negative now compared to trade school.
Kids are just happy to be alive, they don't need a billion things.
