First off, you can survive on minimum wage. What you cannot do is expect a lot of things that are not necessities. You also need to chose where you live. No, you cannot afford an apartment in a major city for yourself, but I know plenty of places where you can get cheap and good housing. Your car will have to be used, if you have one, and you will not be able to get a loan as they will require full insurance coverage. You can forget about a huge cable bill, and if you cut out TV entirely (which is easy today with a less expensive HS internet account.) Don't plan on an Iphone, and deal with a low cost cell over a landline. Credit is only for emergencies, and that does not include any sales.
The reality is that plenty of people cannot imagine living without the expensive perks of a higher paying job, but there are people who do it. You have to learn to cook. You cannot eat out, even fast food has become too expensive. Forget the bar. Forget the movies. Deal with necessities, and stay away from credit as much as possible because any monthly payments are going to kill you fast.
Most kids have hard times with it because they have school loans, a car payment, car insurance, credit card bills which racked up in college, and they are used to living off of parents or friends. To tell the truth I could easily live on a minimum wage job right now. My expenses are rent, internet, car insurance, gas, power, and food. I could eat well for myself on 200 dollars in Food stamps if I had to because i know how to cook and I stay away from a lot of processed snack foods which tend to be pricy, and bad for those with sugar problems. I would probably find a roommate to split things with, and have no trouble making it on a grand a month. I could do even better if i found a nice weather area and picked up a smaller vespa instead of a car.
None of this would be possible if i had school loans, credit card payments, a car payment, or even a standard mortgage. People in the US feel entitled to a whole lot, but you can survive on less luxuries if you had to.
