debt for housing, which is a depreciating asset in normal times (housing wears out, land may become more expensive) is not a great idea, but it has been normalized and when you have negative real rates & inflationary policies, as we had for over a decade, it can make a lot of sense

debt for productive activity in general makes sense if it isn't compounding (mortgages act like simple interest, btw, although it's complicated since you pay more interest at the start of the loan and so if you move within the first five years you've paid almost entirely interest on the home)

debt for consumption is always parasitic

that's why it's insane how hard it is to get a business loan and how easy it is to get a credit card: usurers want suckers, not shared risk on productive investments
