The key is to look at this long term. Understandably, those that are out of work do not have that luxury.
The days of working for a single company for 40 years and retiring are over.....the minute that a company can save a $ by outsourcing, they will, if for no other reason than to stay in business.
By-and-large, the same people that holler about protection buy the cheapest products on the market. The way to produce those cheap products is to import them from overseas. A plant manger in Mexico that I work with summed it up best. He said, "You can pay Americans $9-10 an hour to do these manufacturing jobs, and they'll get pi$$ed off and quit. You can pay Mexicans $9-10 a day to do the same thing, and they'll love it, because it's 2-3x what they could make elsewhere."
And you're absolutely right about the quality of the work, and what comes around goes around. We recently outsourced our service desk to India and the quality has been terrible. We're currently looking to outsource our telecomm and networking - solutions like India have been taken off the table. It'll still get outsourced, but will stay in the USA.
Just as I thought.
