I'm also reminded of Ray Harris' essay "Left, right or just plain wrong." And the follow-up essay, "Thoughts toward an integral political economy." They are still the high moral standard to which integralists should aspire.
Ah, at 29:20 he brings in basing our values on 'realism.' Haidt keeps saying what if conservatives are 'happier' then we must assume it is the better value system. Harris replies: "Actually having our beliefs track reality, however loosely, is better in the long run than being delusional."
At around 40:00 he supports that a better moral response is one that takes account of all humanity instead of one's ethnic group. That is also an answer to Haidt, where conservatives only support their own group's value of religious belief and/or the social Darwinism of takers versus makers. Or in kennlingus, post-conventional morality is better and it doesn't include conventional morality.
At around 42:00 he got a question about judging distribution of wealth by merit or by everyone deserving the same amount. Harris didn't have a good answer. My answer is that nowhere is that a reality in our US system, i.e., no one has ever argued for it, even progressives. Giving food stamps or welfare to those down on their luck is not giving them the same amount as one who works, even at minimum wage. Social programs are at a fraction of minimum wage. And increasing the minimum wage is in no way giving those workers an equitable distribution, just a wage on which they can purchase necessities of life. The argument on merit still applies, i.e, those with more demanding jobs, and with sufficient performance proficiency, earn more. On the other end, there has to be some ratio of top to bottom because being open at the top is what we have, and it leads inevitably to such income inequality that has direct relations to degrading the equal 'opportunity' (not result) for everyone else.
At 47:00 he gives an argument similar to my 'best level' thesis, that we need laws and institutions that hold us to our higher angels even when we don't feel that way. That is the rationale for taxes, that we must give so much for the social good whether we want to or not.
