Your point that growing income inequality as an issue worthy of more focus  is not a bad one.  But its really technology that is driving the problem.  It will only get worse as robots replace workers and even many professionals (consider robots doing surgery and software writing contracts).  The internet will become a source of atoms and algorithms enabling us to manufacture a car in our own garage.

This turns the theories of Karl Marx on their head-- capital rather than labour will become the source of all value.  We are  starting  to see the impact of this now.  So, I am not very persuaded by your pseudo Marxist focus on the 1% which smacks of an anachronism in the face of our current direction.    I suppose profit maximization is driving the technological revolution, and capitalism is the engine of that since it unleashes the creativity of humanity, but surely you are not a Luddite.

But I agree that we must find a way to pay out the technological social dividend fairly.
