FICO to incorporate buy-now-pay-later loans into credit scores

Theoretically, credit should be used for one thing: to make more money. (not less)

However, instead of using it to buy or construct a machine to triple what you can produce in an hour, the average person is using it to delay having to work that hour at all, in exchange for having to work an hour and six minutes sometime later.

At some point, you run out of hours available and the house of cards collapses.

i.e., credit can buy time in the nearly literal sense, you can do an hour's work in half an hour because the money facilitates it, meaning you can now make more money. If instead of investing in work you're spending on play, then you end up with a time deficit.

or, e.g. you can buy 3 franchises in 3 months instead of 3 years (i.e. income from the 1 franchise), trading credit for time to make more money, instead of burning it. It'd have been nice had they taught me this in school.

Do you also think that way about buying a house with a mortgage (credit)? I don't.

A mortgage isn't used to make more money. It's used so people can own a house after saving for a few years, rather than waiting until they've saved for a few decades.

I do. Housing prices are constantly rising, when you take a loan you are buying an asset which (with some luck) may appreciate in value more than mortgage interest rates. That's why in some countries it's worth taking a loan as soon as possible without saving for too long.

Sure, without mortgage you may not be able to afford a house at all but it does not change the fact that mortgage is a "good" loan (i.e. you benefit from taking it)

Mortgages with low interest rates are also one of the (main) reasons houses are so "expensive" in the first place.

The cheaper money (credit) is, the "higher" the prices will go.

It's not so much that houses became expensive, it's more that money to buy a house (specifically mortgages) became relatively cheaper. Low interest rates did that.
