When you think of policies that are going to address inequality of wealth, you have to be very thoughtful about what economists call "incidence of taxes." If most of the savings is being done by capitalists, and you tax the return on capital, then they will have less to invest. That would mean, over the long run, that the rate of interest would go up. That would therefore undo some of the intent to lower the income of capitalists.
