Sadly, having more money doesn’t buy time. At least, not until you have enough money that you can hire assistants, but that’s pretty extreme.
Hiring a housekeeper to come every couple of weeks has pretty much directly bought me time, at a pretty reasonable price. I like living in a neat and tidy home, but never cared much for scrubbing grout or polishing the stovetop in my free hours. I’m delighted every time she comes, and I never wake up Saturday thinking I’ll have to vacuum under the couch cushions.
Enough money to not work and care for your children is the correct answer.
But sadly the people I know who made enough money to be able to retire young are workaholics that will hire people to raise their kids. Because their workaholism is what made them rich in the first place. See Elon for an extreme example, I doubt he can even name all his biological children.
Who needs assistants? I'll make do with enough money to draw a monthly stipend covering my expenses and leisure from for life. You know, like a salary, but without wasting my time on pointless tasks that give me no satisfaction.
I mean, it does for people like me who decide to work less as they don't need to earn as much.
I know a lot of people who DoorDash, have groceries delivered, have a house cleaner, and call a contractor for every small thing that needs to be done. They’re buying time.
It’s never quite as much time as expected, though. Each is a marginal addition of free time that brings its own complications (like my friend who did an alarming amount of DoorDash and is now investing a lot of time into dropping weight and managing cholesterol and blood sugar)
