Tom Mulcair is harkening back to the NDP's social democratic roots, casting his party as the champion of working class Canadians and the bane of what he calls corporate "freeloaders."
By contrast to the NDP's worker-friendly policies, Mulcair portrays Conservatives and Liberals alike as hostile to and contemptuous of the labour movement, which he credits with driving "the greatest reduction of inequality in human history" over the past century.

Meanwhile, he says Conservatives and Liberals have doled out "tax cuts by the billions" to the largest, most profitable corporations — cuts he has promised an NDP government would roll back.

"Today, the only ones in our society not paying their fair share are corporations," Mulcair says.
