After all the layers of subcontractors had taken their cut, there was next to nothing left for the people doing the work. For instance, the author Mike Davis tracked the way FEMA paid Shaw $175 a square foot to install blue tarps on damaged roofs, even though the tarps themselves were provided by the government. Once all the subcontractors took their share, the workers who actually hammered in the tarps were paid as little as $2 a square foot. “Every level of the contracting food chain, in other words, is grotesquely overfed except the bottom rung,” Davis wrote, “where the actual work is carried out.”
