We've been hearing our political leaders say for decades that losing existing manufacturing jobs wasn't a problem because the next generation of jobs and industries would replace them and we needed to educate our workforce to prepare for them. Well the next generation of jobs are also going overseas too, and for the same reason. Cheap labor. Manufacturing, IT, Financial, Medical, all those careers are being gutted by overseas resources and foreigners brought in.
Except that was the case in the 1800s as well. US ALWAYS has had higher wages because of available land and entrepreneurial culture. How about this: cite me some foreign nations now stealing menial jobs who have a growing middle class.
