[T]o talk about socialism as a function of practical politics means gliding past its underlying appeal. After all, there are countless other ideologies that can be similarly reduced to the desire for power expressed by certain elites or certain segments of the aggrieved masses themselves. The most obvious example is, of course, nationalism, which has more in common with socialism than is ordinarily believed. From the French Jacobins to the Italian Fascists, nationalists tend to be in favor of state-directed economics, the redistribution of wealth, and a collectivist or communal organization of society. What unites all of these movements is a sense that liberal democratic capitalism doesn't provide a sense of social solidarity. It is too atomizing, too cut-throat, and mostly unconcerned with how we should all live together.
