This sounds like the same stuff we heard before Ronald Reagan made the statement that "Nobody is going to be starving in America". And, he was right; nobody did. We heard it again when the Republican congress presented a welfare reform bill to Bill Clinton (which he surprisingly signed). And yet, nobody is starving.
We have tons of illegal immigrants flooding over our borders to take on those "less than living wage" jobs that supposedly nobody wants. And, they seem to be living on them and have enough to send a few dollars back to Mexico to finance the next flood.
As far as "union goons" threatening violence to get their way, it sounds a lot like Jesse Jackson's antics. The problem here is that violence will bring on counter violence. I am a firm believer in the second amendment and the right to self defense. So send your terrorist goons over here.
Now, don't get me wrong; I have nothing against collective bargaining, but I also have nothing against people choosing to bargain for themselves as an individual. People have the right to associate freely with whomever they wish. And, if they wish to stop working, by all means let them do so. And if they wish to convince others that their cause is rightious, by all means let them do so. But the minute they threaten other people or other people's property, they are out of line. And the minute they try to prevent someone from working if they choose to do so, they are out of line.
