Nobody who is truly poor would skip out on the last month rent unless they were desperate, because the landlord will find things wrong with the apartment and will charge you the most or all of the security deposit. Then they will file an unpaid dept claim, turn it over to a debt collection agency and it will hit your credit score. Which means in the future you have to rent in the really scary parts of the city, and if you don't want to rent in the really scary part of the city you'll pay your last month's rent. Also a lot of jobs check credit scores, a bad report could keep the author from getting hired.
In regard to the car, the author doesn't have the credit score or income level to even qualify for the lease let alone, "the cheapest lease deals", not to mention the author certainly doesn't have the $3K down payment. If you are thinking that they can just roll the down payment into the lease, well they only let you do that if you have the best credit score.
Also deposits are always(by law) held by a third party in escrow, and it's actually a bit of a pain to claim any money from that as a landlord, so it's really rare that people lose their deposits unless the place is absolutely wrecked.
Don't confuse suing with winning. You can sue someone and lose, but the lawyers will still cost both sides a lot of money.
Give them your buddies contact information.
Someone who can write that well can probably find ways to make more money if he needs it - what else is he trying to deceive us about?
