Manufacturing has largely moved offshore, at least for the vast majority of the jobs. So if we are rapidly offshoring (and thusly equally rapidly not doing) accounting, engineering, software, call-center work, reading and interpreting medical data, financial planning, and soon enough medical doctor and lawyering work; and if immigrants are doing transportation, agriculture, and the remaining other low-tech work; and if robotics will be completely eliminating 90% of retail sales jobs with RFID technology.....
....then tell me what other 'trick' we will be ponying up for our paychecks, please?
