When I see how people spend money they don't have, I'm always wondering if their parents never sang for them when they were young, or if they are of a particular dim nature.
Sure, I can see why some people would take out a loan for big things like a house.. But for just about everything else? No. Either you can afford it or you can't.
"But I need a car!" Yes, but you don't need a car you can't save up for, you need a car you CAN save up for.
"But old cars break down and are expensive to get repaired" Yes, but you don't have money to pay someone else to repair it, old cars have cheap parts and are relatively simpler to repair, learn how to do it, you're not in a position to be fussy about what skills are beneath you if you can't pay someone else to do it, stop thinking so highly of yourself and get to it!
When I see the option to finance a sandwich, my brain just melts.. No! If you don't have money for fast-food, then go to the grocery store and buy the ingredients yourself, you can make a weeks worth of sandwiches for what one ready-made one cost.
