Unionization tends to make labor more expensive because workers demand a fair wage and benefits. Unionization takes power away from owners. If owners can't make enough to pay fair wages and benefits then, in my opinion, they should go out of business (union or not).
I don't believe your example of working in a union.
The costs on the American continent reflect the true cost of making something (i.e. includes paying for externalities and a safe work place). We should be appalled at and boycott those companies that do business in places like Hong Kong where limbs are severed daily and the worker is tossed into the scrap heap.

You still haven't answered Nick's question. You did use the moment to reiterate your already stated opinion, but you didn't actually add anything to the discussion you hijacked.
