I recently got a job that was supposed to be part time, but thanks to a few other employees being unavailable for an extended period of time (and thanks to my extraordinary work ethics), I'm currently working 35+ hours a week. Sure it's minimum wage ($9.19 per hour; WA > your state), but the expense I have is rent, and I'm living with my parents and they only have me pay $100 a month.
Money piles up fast when you don't have to spend any of it. I might build a nice computer or buy a nice sword, but for the most part I'm just hoarding it. Of course I hate the job though; basically I'm a waiter in a retirement home and I have to put up with grumpy unhappy dissatisfied old people's shit for three meals in a row. Thankfully I'm only doing this while I wait to be shipped off to USAF basic training; it's nice knowing that it's temporary.
