Why tell the world about it???
Ad revenue. Hopefully. Well, at least, for the author. Or, at least, "exposure." Exposure and $1.06 (depending on local sales tax) will buy you something from the dollar menu!
...leading to naive young people who think nothing of applying for multiple credit cards to get free t-shirts...
I, uh... yeah. Freshman year. Free tshirt. Still have the card, though! Discover, with 5% cash back (not sure what it was back then, like I'd have paid any attention).
She bought a condo and didn't figure out until afterwords that she didn't actually make enough money to cover the mortgage and HOA payments???
The better question is, "Why didn't the bank figure this out before giving her the money?" Then you start to realize when this was, and why "giving mortgages to people who can't pay them, bundling them together, and pretending they're high grade investments" worked as well as it did come, oh, 2008 or so.
I stopped after the story about buying the condo on the 40k salary. How as a single individual do you continue dating someone with that much debt and then decide it's a good idea to marry them after seeing no improvement in their behavior? I just feel bad for this husband who was apparently the "Frugal" one...
No idea. My wife is radically better at "not spending money" than I am, and I wouldn't have married her were this not the case.
And I do use my debit since I don't have a real credit card...
Travel is a good reason to use a credit card, IMO. The authorize amounts on the cards tying up money for a while are annoying, and I've had my credit card stolen a few times, usually after travel. "There's a couple grand of charges on my card that I didn't authorize, we're shipping you a new card" is slightly annoying, but "My bank account is a couple grand low and my rent check just bounced, along with the utility payment" would be radically more annoying to me. I know I'm not liable for fraudulent charges, but there's a whole boatload of trouble my bank account missing a few grand could cause, and I'm not sure how my bank would view that, or how my landlord would have viewed that.
