Until recent history ( and I do mean rather recent history !), those who worked in some form of manufacturing, were laid off at the will of the owner. Get mangled in a machine? TOUGH LUCK...you were fired and no, you didn't get any severance pay nor medical benefits. Go out on strike? You would get shot/fired on and absolutely have no job to go back to! New immigrant waves? Hold on to you hat, whoa Nellie...you were OUT ON YOUR EAR, because the new immigrants would work for less! Outsourcing? That isn't "new" either!
And owning your own home, was, until very recently, something only that most could only dream of.
