Why do people spend so much money?

It's disgusting how many people spend money that can't afford it. Why do people spend money on cellphones, cable, Internet, expensive cars, etc that can't afford to pay for healthcare, loans, etc? It really confuses me. Some of the people who can't pay have nicer phones, cars, and clothes than I.

It's not everyone, but the patients I see with iPhones as they are filling out our hospital's program forms to help write off the bills is sickening. I saw the same thing with people who had food stamps when I worked in a grocery store.

What are the steps to creating a content discovery engine?

IPhone 5 using way too much data?

I got my iPhone 5 in December and it uses so much data I've had to bump up my data plan to 10MB a month and yet still am nearly going over every month. I've read every post about this and every solution that is stated I've already done and it hasn't changed a thing. I use Wi-Fi every moment I can. I'm to the point where the only option is to shut it off completely, which I need to be able to get a hold of. Hopefully someone can at least tell me they're dealing with the same thing or tell me something I haven't already tried. BTW, it's a Verizon and it is not jailbroken.
