The waning of the working class needs a response in a new form of communist thinking. Communism has no intrinsic connection to the working class. It is possible and possibly more effective to consider a universal class, that is, the principle of equality, as the basis for a generalized class association that acts according to principles. The focus on the working class was a tactic, and a brilliant one, but a tactic that subtly violates the principle of equality. Why should the working class be favored? In the end because it is a majority. But then why not consider a majority as the universal class. That includes the working class, and is also compatible with renewed working class emphasis.
As the working class wanes in the forms of economy emerging a more effective approach would be to simply create one universal membership and apply social principles such as equality to the one class.
