Well, you live in a town with a lack of well paying jobs, most likely you don't have an education, because if you did, you can find a decent job in any town or city. No body told you to have kids you can't support. That is the bed you've made and now, you must lie in it.
Are you telling me that you don't blow $50 a month on things you don't need? Whether it be soda, cigarettes, coffee, or what ever. This is your money that you can invest. Its not our fault you decide to spend this money on something that is not needed.
$50 a month might not sound like a lot, but its $600 a year. If you are investing it, whether it be in the market, a 401k, or just a savings account, this money will add up. Everybody has money they can save. Some may have more than others.
I am one of those people that works paycheck to paycheck as well, but I understand it is my own fault. I blow my money on things that are not needed, and thats why I don't have a bunch of extra money lying around. I quit a well paying job, close to $80,000 a year, simply because I hated what I was doing. 60hrs a week just isn't for me. But it is my choice I am broke, just like it is your choice. Move to a different city with more work, get an education so you can find another job, etc. There is no one to blame for your misfortune other than yourself.
