What other product can you purchase, and have the price change after you purchase the product? Money is not purchased when it is loaned. It is rented, and lots of rented goods have rate changes.
And, yes, money is rented via credit cards, but every purchase that I make with a credit card is in effect subject to a variable cost, because the interest rate that I'm being charged varies. So, I might buy a $1000 computer, thinking that I'll pay it off in on year at %10.
If my interest rate suddenly goes up to %29, I'm now paying closer to $1300 for the computer that I was planning on paying $1100 for.
And, furthermore, I have little recourse when my interest rates go up. I say that it's only because of the obscurity of the terms that people put up with this. If the same thing happened to people's car payments or rent payments, they'd be up in arms.
