What we should accept is that the time is approaching where a) it is possible for skill and lucky people to make many millions of times more money than those who are neither and that b) the cost communication has decreased so much that in many cases it no longer makes sense to employ people, instead it makes more sense to contract the work out.
This means we should do two things: stop talking about income differences and focus on making sure the poorest have tolerable lives and b) make it much, much, much easier to start your own small business. This means tax cuts but above all simplifications of the relevant law.
