Who benefitted from this type of work?

The people who benefitted from this type of work were the coal mine owners, the electric companies and the people who use electricity. The coal mine owners benefit because they get to employ people for below minimum wage and young kids who are flexible and can work for hours on end. The electric companies benefitted becuase they got a lot of coal and fast because of the use of Hurriers and the transport systems they use. Finally people who use electric are benefitted becuase they get electricity and without Hurriers collected the coal would be a long and tedious task which would delay the source of coal.
