Human experience simply cannot be averaged over large spans of times while ignoring the extremes. Dipping into the red means permanent damage. Imagine applying this line of thinking to your bank account -- "sure I spent $500k in two years on fast cars and fancy bars, but averaged over 80 years of paying small amounts of interest, the bank should be glad to make the sacrifice of stability in favor of efficiency."

"Sure I spent $500k in two years, but I've been in the positive and saving for 80 years".

The pandemic was just a blip on the radar, a period of adjustment we still don't understand fully economically, but it was not a Great Depression as it lasted only a couple months and affected just a part of the population (layoffs, but with goverment safety nets)

umm... this is kind of the purpose of banks... get car now, enjoy car now, pay 3%, inflation is 5%. If you buy the car cash you pay more, and get it later.

Lets take a C8 Stringray @ $100K, if you buy it today, it will cost $107K over 5 years. In five years it will cost you $128K.

No bank will let you go on a $500k spending binge when you've never had more than $5k in your account. And no amount of averaging over a lifetime will make up for the fact that rent is due now.
