Using a credit card is not the same as borrowing money as long as you pay it off in full every month. You can do that and still build up your credit score.
To what end? A good credit score only says you are good at borrowing money when it comes to returning it back to whom you borrowed it from.
I do understand that lots of businesses do use the leverage all the time. Net 90 or even 120 days from invoice is common with many large companies. If the amounts are large enough they keep the interest gained from the time delay paying the debt they owed. Ah, the cost of doing business..
It’s a false gain because all of us that deal with them already build that into the initial price. If you walked in from the street and paid cash, you would get the same thing for less.
Thats why credit card businesses wanted to make “fees” illegal (you do know they charge the retailer too, not just the consumer that pays the interest, right?). That’s why many give “cash discounts” as a way to “game” the laws the more powerful lobbyists have had put in place.
The only folks that have put a better scheme in place have email addresses ending with .gov. Cost you when you make it, when you spend it, if you save it and when you die, win, win, win, win...just not for you.
