Too bad Slywyn was offended, because I thought xiaomei's comment was quite funny and very true.
I am interested to know what your take is.
Honestly, I don't think the remedies are all that mysterious. Most of it comes down to addressing poverty in general through the kinds of "socialist" programs that the right wing tends to hate -- a livable minimum wage, limitations to the offshoring of labor and a protected right to unionize, and accessible good-quality education and health care for all members of society -- in combination with a few specific measures to prevent racist bias from skewing those attempts to address poverty (specific forms of affirmative action, for instance, which of course is a popular right-wing "this is the Real Racism" target precisely because it in fact works; it might also be nice to see some real measures in place to monitor attempts to physically ghettoize minority communities, "redlining" and other such).
We pretty much already know what works, and what needs to be applied. There's no small amount of research available to back it up. The trick is getting the rational solutions implemented in a setting where a certain stripe of politicians opposed to those solutions can use the irrational lever of racism as a means to build support around their own agendas. This basically is a large part of the story of the conservative movement; when the long-suffering black ghettoes finally started to explode in the Sixties, it impelled both the Great Society agenda on the "left" and the rise of the Southern Strategy-based GOP on the right. It was a case of building with one hand and destroying with the other, which is why so much of the black community is still stuck where it is today.
So the real question is: how do you beat back racism far enough for the old right-wing scare strategies to stop working and solutions to become politically possible? As far as I can tell there is no easy answer to that except to keep confronting it, and wearing away at it, until its power is broken. We are approaching
that watershed, I think -- the election of Obama was a major early indicator -- but there's a long way to go yet.
(Xiamoei's post above again is excellent.)
