I know a few people who maxed out multiple credit cards in our early/mid 20s buying big screen tvs, hella nice furniture, expensive sound systems for their cars, and shit like that. Some of them had their credit pretty much ruined and I think one dude is still paying some of it back 10 years later (he maxed out like 6-7 cards at $5000 a piece).
I really don't have much sympathy for people that live outside their means then bitch and moan after they buy a bunch of shit they couldn't actually afford and go into debt and fuck up their credit.
