If a person takes a minimum wage job and they're still working at it 5 years later for 50 cents more an hour, they would be someone who lacks any intelligence or ambition. As a Boy Scout leader, I deal with a lot of teenagers. When they get a job making minimum wage, they typically get a raise from anywhere between their first 3 months and first year. Most of them eventually take their work experience and find a better job paying more. It's how real life works. These kids are in school and living at home. They have minimum wage jobs because they have no work experience and they need pocket money. If you are a married person with children, a mortgage, car payments, etc. and all you can find is a minimum wage job, then you need to start expanding your range and be willing to uproot and move to where there is a good job. I don't blame an employer who has a minimum wage job for continuing to pay minimum wage. I blame the worker who thinks a minimum wage job is supposed to morph into a living wage job. That can happen if the employer has additional higher paying jobs and you do a good enough job to be moved into them as you gain more knowledge and experience. But if you work for a nursery digging holes to plant trees.....you may be the best hole digger in the world, but your pay is going to remain pretty much the same.
Certainly that makes more sense than accepting the fact that some people are just not capable of more, and oh yeah SOMEONE has to do those jobs anyway, may as well ensure that those who are don't have to go on welfare to help make ends meet.
Here is what makes sense. Just about anyone who isn't physically or mentally handicapped can bag groceries, dig holes or take movie tickets. Doing brain surgery requires a bit more effort and ability. Different jobs have different worths and different pay. A guy who owns a gorcery store knows that he will have a constant influx of new employees made up of teenagers getting their first job or housewives bringing in a little extra income. That is who he hires and he knows that he won't be handing any of them a gold watch after 30 years of loyal service. Minimum wage jobs fill a vital role in our economy, but they are a springboard. They are the kindergarten of jobs. It takes a lot to get from there to a PHD. You take a low paying starter job doing menial labor that any other person on t he face of the earth can do. If you do a good job, you'll most likely get a bump in pay. If you're really good and there are better high paying jobs in the company, you can probably move up and make more pay as they come available. Or you hear from your friend that the warehouse he works at is hiring and they pay $10 an hour and you go apply. The manager interviews you and looks at the work experience you've built up and decides to hire you. You graduate high school and because you and/or your family don't have a lot of money, you choose the vo-tech or community college. You study plumbing, HVAC, etc. or you take EMT training or get an associates in accounting. You find a job making more than your $10 per hour warehouse job you did as a kid. Then you lather, rinse and repeat.
Now tell me how it's the grocery store owner's fault that you don't take some personal initiative to better yourself over time.
