We don't have to be angrier than they are. We simply have to realize where the liberal/Democratic emphasis on equality, properly understood, would take society: maximum liberty and a self-regulating economy with no unemployment, poverty, or taxes/public debt while sustainability would be increased. The one necessary change within the existing economic system to accomplish all that could be instituted with a single legislative Act.
All of that would be accomplished without imposing any cost on employers, without having to redistribute anything, without imposing any limit on income/wealth, without additional regulation of the economy, and without requiring people to act any particular way. In short, any potential opposition would not have a political leg on which to stand.
For all of that, "Equality Is All We Need" (here in Medium, but not behind the paywall).
