It’s a long read, but worth it!
Yes, it is worth the read. Of course, Haith’s analysis quoted in the middle of the piecce is severely flawed. If “Liberals” really based their morality on “Harm/Care” the fact that leftist ideas inevitably lead to harm would give them pause. And, depending on what one means by “Fairness/Reciprocity”, one can argue that capitalist ideas are based on a notion of reciprocity and fairness, while the leveling impulse, while it embodies a notion of fairness absolutely denies reciprocity in human interaction.
Personally I think leftism is caused by a severe failure to understand economics—if economics were a zero-sum game and static rather than dynamic (the two errors leftists most commonly make) their ideas might arguably have some merit. Either that or, if new research holds up, it’s a result of defective dopamine receptors.
