Apples and oranges. How many people have been held up at the 'counter' on an assembly line? Dealing with the public is pleasant?--not in most jobs, there is a minimum of an a$$hole a day, and those jobs pay minimum wage in my town.
Tweaking the sentence to include dentist/doctor/lawyer for wage comparisons does diddley-squat on my credibility meter, too.
Permit me to counter with this:
If your source for even one most basic item essential for the national defense is a potential enemy, you are bent over in the bathhouse with your skivvies around your ankles. It is only a matter of time.
If one looks at issues of Popular Mechanics from the 1930's, ads for home workshops (mills and lathes--metal not wood) abound, as well as plans for "build your own bulldozer" and similar items. That was the generation that fought WWII in the factories as well as on the battlefields.
What are we going to do now? throw CDs at them?
Don't let the dollar value barometer fool you either. Just because they produce cheap items does not mean they are not important items, especially when a plastic box full of $1 DVDs, (a whole season!-prerecorded!) sells for $79.95 at WalMart, about the same at an imported SKS rifle used to. In a crunch, what will be worth more?
Either people are free to choose where they work or they are slaves. Having the government force people back into factories either by taxes or by law is both wasteful and wrong. We need fewer laws and taxes not more, and we need more freedom not less.
