This falls apart when you want to get married and have kids? It’s certainly possible to find a frugal partner but kids still cost a lot of money in general
I agree but IMO there is still a huge amount of discretion involved. My wife and I are routinely stunned at what other families spend on their kids clothing, hobbies, family vacations, etc. We hear a lot of grumbling from our kids about it too, but we both feel it is better both for our wallets and the kid’s upbringing.
