I often hear this type of thing from those who haven't learned about economics. Here's the thing, you have labor and you sell it to your employer. If you are unhappy with the price you are receiving and you think your labor is worth more, then find a new buyer.
You're employer does not set the price of your labor. He agrees to the price you set. If he values your labor more than the price he's paying for it, he will continue to buy it. If not, you need to find a new buyer or increase the quality of your labor. In fact, in a tough economy, good labor is worth more than ever!
Now, this is what you can do now. But to affect the situation on a real scale, you need to have a huge field of potential buyers - that's where the wealthy are playing you. They pull all the strings they can utilizing the government to ensure that you cannot find other buyers. They call it competition - they don't like it. They use government to reduce competition for goods, services, and yes, labor.
