Ever heard of WAGE SLAVERY?
What corporation is forcing someone to work for them against their will? One can hardly be considered a slave while working for a corporation if they are free to quit.
How can someone be free to quit, when even one month without job will severely create problem from paying bank student loan interest, house interest, vehicle loan interest and much more...
This fear that is present in this crony capitalistic world makes people not to leave job even if they wish..
