Management fees are labor income. Interest is investment income. I have no desire to eliminate any of this, except for the portions that are economic rents. As an example of the portion that is a real rent, consider the management fees you pay on 401k investments over and above the management fees paid on equivalent public symbols. (E.g., my last 401k's S&P index fund cost 30 or 40 bps more than SPY.) I favor eliminating this rent by banning 401k's. Is that what you had in mind?
