Maybe in the context of this article, but that's not what it logically means.
You're "in debt" when your liabilities exceed your assets. You have negative equity, and so these debts are claims against your future income.
That's what "in debt" means, in a nutshell: your future income belongs to someone else.
If we are going to write a story about how some population segment is "in debt", but we label everyone as "in debt" if they have any credit card balance, that is blatantly dishonest.
"In debt" is a loaded phrase which means that the interests against you exceed your assets. It's a common term, for which the more formal word is "deficit".
That's the interesting thing if you want a story on lots of people being in some kind of financial strain.
A temporary loan purely for transactional or cash flow convenience does not represent any sort of financial strain.
Then you're using credit for convenience, not as a loan because you don't have money.
People using crdit strictly for convenience, always paying their bill within the interest-free grace period, are not in debt (on account of that credit card).
Even people with significant loans are not necessarily in debt. If you borrowed $300K to buy a $400K home that is now worth $500, you still have a loan, but that is offset by equity in the property. It's not the same as borrowing to buy food, which is consumed and gone.
If you're successfully paying off your CC, then what are you paying off if it's not debt?
IMO, to be in someone's debt means you have to pay them back, which is regardless of what cash you have.
Are you trying to say that if I borrow money from someone and I actually have the cash to pay them back, then I'm not actually in their debt?
"In debt" is a loaded term which actually refers to a deficit situation, rather than the mere existence of loans. If we say, "OMG, X% of Americans are in debt", the reasonable interpretation is that are under financial strain due to actually running a deficit, not that some of them owe their friend ten bucks for yesterday's lunch because they forgot their wallet at the office.
If you have the self discipline to not spend more than you make putting everything on a card and paying it down to 0 every month makes a lot of sense.
Sure you could screw up and wind up making monthly payments if you spend more than you make but that's not fundamentally any different than if you bought all the essentials in cash then put the rest on credit.
The article is intentionally misleading by talking about people "paying for things" with credit cards and then talking about credit card debt (no mention of how much gets paid back before the end of the month) implying that the month to month balance people are carrying is a result of necessities rather than large purchases.
This entire article is one large assertion followed by flimsy support after another.
