-- Similarly
exploited immigrant labor without labor rights (all temporary and dual purpose immigrants), employer sponsorship being the key to suppressing wages (plus all of David Card's papers and equations are wrong due to DNWR)-- Fair Labor Standards Act generally doesn't apply to office workers and other positions that corporations tag as professionals and / or managers, despite recent Obama hike of minimum applicable wage.
For example: Is our economy ruined because of
immigrants coming to our country, or is it ruined because the companies who are supposed to be boosting our economy with new jobs are instead giving those jobs to cheaper
labor that can be
exploited for wages far less than minimum?
