Why have kids if you don't want to spend time and $$$ on them? They ain't the cheapest hobby.
If you really want to go "back in the day", we used have 5-7-9 kids, knowing that we would have a few die along the way, bet most of the raised up to the point they were somewhat useful on the farm, then see them married off over 15-20 years, just about the time the parents were ready to kick the bucket, or get killed in an industrial/farming accident.
I raised my kids outdoors, for the most part, as best as I could. They never played video games, they all could hunt and fish, all killed their first deer at age 12. All could kayak Class IV rivers by the time they were 10... And, I spent a ton of money on hunting, fishing, rafting gear and trips for them. Money that I didn't spend on flying.
The point is not if you think travel sports are a good use of $$$, the point, likely, that is relevant here, is the $$$$ spent on GA that are not available for the kids. And, is that a good use of finite family resources.
Each family decides, but, I can tell you that our local soccer fields are busier than our local airport, so, it looks like the masses have spoken.
