Not sure the argument holds: conservatives AND progressives alike claim to fight for justice (equality or equity? you choose), and for dignity (is it social or individual?) and wealth.

Everyone on the left already agrees on what these words mean for them, but that doesn't make this a strong political argument to build on, if we actually want to challenge our opponents (the obscenely wealthy)

This might read more like a tribal affirmation than a call to action.
