One way to encourage that is to require all government contracts to be filled by Union shops onlydavis bacon act allows union shops to bid at a comparable cost as non union, because the pay rate matches the union rate. Now I would like davis bacon be applied to IT work as well. That way you dont have multinationals paying $6 an hour to Ukrainian programmers to build the Obama Care website (cough)and pocketing a ton. Good american programmers need the work.
