I strongly disagree.  The labor practices may be legal, but that doesn't make them fair.  In fact, the processes by which the regulations were changed were unfair also.

Just because Wal-mart isn't the only one doing it and the change has to go beyond them, doesn't mean we shouldn't criticize them for it.  We must call out the companies who indulge in this to highlight the real-world consequences of our current system.

Wal-mart's business practices are unfair -- they're just not unique.

Maybe we can eventually make language a complete impediment to understanding. -Hobbes
