Don't ever live on borrowed money.
I grew up in the depression and I was taught to never borrow money except for a 1st home.
I've lived by that for 77 years including running a business without ever borrowing a cent for anything,
If you haven't got the money you don't need it.
In over 40 years in a construction business averaging 25 employees over the years I can't think of more than 4 that had a pot to piss in because they borrowed money to buy things.
Yeah, Americans should purchase their homes and cars with cold cash...lol...
I imagine a lot of first time buyers will be in their 60s or 70s, if their health holds up...
