A land tax would be better at promoting equality than to subsidise poverty

We can encourage equality not by promoting the poor, but by placing restrictions on the advantaged that specifically open up the opportunities for the rest. Rather than subsidies, if dominant players are prevented from entering a market then this gives a chance to smaller groups. If the advantaged are forced to relinquish their position of superiority, then others will populate it and this can be preferable if there is a plurality of people who gain.

Disincentives are more effective than incentives at promoting Social harmony. To encourage equality we should discourage individual wealth, not subsidise poverty, since as far as forms of stored material wealth are concerned, there is an upper bound.
