Converting the white working class is a laudable goal. It is not easy one. They are ingrained in a culture where some amount of authoritarianism is comfortable from them, especially in the workplace.  The left has to demonstrate that something like Democratic or Coopertive Socialism can also deliver cash and prizes while maintaining their dignity.  Those who are also deeply ingrained racists/sexists/homophobes are harder to help. Only by humanizing the Other can this be done, although there is considerable resistance (and the Church is not helping). That some of this discrimination is economic is Marxist and is also true, especially where Latino immigrants are brought here illegally to work in the shadows.
