Two tier work force II

Recently many companies are subcontracting work out that had formerly been done in-house. The USX Corporation, for example lowered the number of in-house hours of labor needed to produce a ton of steel from 10 in 1982 to 2 in 2010, in part by subcontracting out maintenance-type jobs. Rather than pay a pipe-fitter a reasonable wage plus benefits the company got the same work done by a smaller company that paid its workers less than the minimum wage and provided no benefits.
