They didn't even update the "workers" rhetoric. Today the left is the un-employed and gov-employed no'bility, not the workers. They want to progressively enslave the few remaining workers to serve them. Leftist voters are allergic to work and can't relate.
Let me extend that to "allergic to real work"... Unions are part of the leftist coalition. Union members in the private sector work, but they want exclusionary, above market compensation. Union members in government (SEIU, NEA, etc) do relatively less work. The common alliance is of the government-affiliated rich and those who want more for their work than it is worth. I guess that includes the chronically and happily unemployed as well as those voluntarily on welfare.
