Reconciling free market libertarianism and libertarian socialism should never be a matter of ignoring differences. Instead, such reconciliation ought to be understood as building a synthesis. Intelligent argument is an essential part of that process. What’s not productive is straying outside logical discourse, and that happens on both sides.
Let’s take the bitterly-disputed concept of wage slavery as an example of where an opportunity for synthesis can be shown.
We can distinguish between wage labor and wage slavery.
The state acts to involuntarily transfer wealth from the productive class to a political class elite, thereby monopolizing/cartelizing capital. Additionally, the state forcibly cuts off opportunities for economic self-sufficiency. The result is that people are forcibly denied any alternative but to sell labor artificially cheaply in a buyer’s market, where the buyers are a political class plutocracy gorged on stolen loot and enjoying economic influence they are not rightly due.
Unfortunately, in the debates among anarchists, we’ve got two sides exhibiting roughly equal degrees of obstinant closed-mindedness…
1) Those who rightly oppose wage slavery and wrongly blame exchange.
2) Those who rightly defend exchange and wrongly fail to recognize wage slavery.
And it doesn’t have to be that way.
