I'm not sure how we have gotten to the point in this country where employees think it is the employers obligation to make sure they can provide for their family. If you are working somewhere and are not happy with the wages you are earning, then learn a trade or a skill that will pay you more. Get a better education and improve your earning potential. It has never been easier to get student loans and/or grants that don't have to be paid back. It is not the employers job to improve your family's quality of life----it is yours!
All this talk about how much a corporation makes has no bearing on what its employees SHOULD make. This mentalitiy comes from a lifetime of being accustomed to signing the back of a paycheck, not the front. If you don't like how much you are earning, take responsibility for yourself and learn a trade or a skill that sets you apart from others. You will never make much more than minimum wage doing jobs anyone can do.
Just my 2 pennies worth, for what it's worth. :)l
