Yeah, I’m willing to entertain the idea that there’s a tradeof to be made between the short term and the long term or something like that… but to be honest, I don’t think the people who push these ideas are even thinking along those lines. I think a rational discussion would just be a net plus for everyone involved, but people are unwilling to do that either because it’s not in their interest to do so (lobby groups, media agencies) or because they don’t understand why they should.
Don’t get me wrong, I do think there are some left-wing groups who have had discussions on how to best change things. But mostly I think that people are just unwilling to criticize their own side, allowing the craziest voices to rise to the top.
The closest thing I’ve seen to anyone seriously discussing these ideas was when Bill Maher suggested that the US needs a “tea party of the left”, full of people so batshit crazy that they make people like him look like the reasonable ones. So maybe I’m not giving progressives enough credit and they did actually did do a calculation along those lines at one point, and decided that people being temporarily miserable was a worthwhile sacrifice. But for the most part, I think it’s just been reflexive partisanship, and little else.
