Nice to see someone who looks into this in better detail.

Another thing I think we should consider is that as innovation drives up the productivity per person, inequality will always rise, significantly.

The value of a mostly unproductive person will remain very low, while the highly productive will go even higher, so the gap will grow. This is normal, but the problem is that people also now have the ability to destroy value in even greater amounts than before, in the way that lottery winners and subprime borrowers can destroy value. I think this is even more important to address than just taxing progressively on earnings. It doesn't even have to be a tax, it could simply be a throttle on the ability for some to move money around in a bad way.
