A good friend of mine once told me that your only worth what YOU think your worth. If you think that your worth more then 12 bucks an hour then you will get to where you want to be one way or another. When I finished my apprenticship my boss told me (off the record) that I should get out there in the world and work in alot of different shops to round out my skills. He was right. In the next few years I worked in several different shops and learned alot of new stuff. I never looked back and never settled for less money everytime I made a move. By the way where I live 12 bucks an hour is starting pay for a machine operator. That's a cycle start person who just puts the parts in the machine and hits the big green button!
Be carefull what you wish for, you might get it.
