Seriously? "Nobody held a gun to their head" is your criterion? For guys and gals fresh out of high school?
Will you also tell me that employees can't sue for unpaid overtime, hazardous work environment, sexual harassment etc. because nobody held a gun and they could always quit? Such sheep, those common workers.
Its actually amusing; these captains of industry were such sheep when they were young. Makes you wonder when they grew a backbone, if at all.
