Democrats Criticize Wal-Mart? Really?

I saw an interesting article titled Divided Democrats unite to criticize Wal-Mart which includes the following gem:

"We're all together today in wanting to wake up Wal-Mart and say, 'Treat your workers fairly,"' Lieberman told several hundred people gathered outside in stifling heat. He later added, "It is time for the American people to get together to support Democrats who support working people."

First, what does it mean to treat workers "fairly". It is such a subjective term with no real meaning. Some might say it means a "living wage" or making sure that employees are given full health benefits. In all reality these people hate free markets and the right of individuals to work where they want and when they want for the amount of money they want. So Wal-Mart does not pay enough? You have the right to get another job. And what about "working people" can you imagine the possibilities available to define that phrase? Why has everyone forgotten about social mobility? If someone has a relatively small skill set and has a sub-par value in the labor market they can probably get a job at a Wal-Mart and if you desired could work hard, prove themselves, and maybe move up the ladder. Of course there are no guarantees, but there are great opportunities available to those who choose to not be cast aside as a poor hopeless worker who will forever be part of the "working class" forever beholden to the anti-market left.
