Welcome to the forum!
I'm a 71 year old gay white man; I've worked in education and social service, and have followed the discussions around various liberation, equality, and civil rights groups since the 1960s. Some of the discussions have become incoherent to me--the transgender one, for one. I've heard an on-going discussion about race; I don't think it has every stopped entirely. It also hasn't been well informed, a good share of the time.
For instance, most people (white or black) are not aware of how discrimination against black people was structured from the 1930s forward. During the depression the Roosevelt set out to organize a vast housing project -- now known as the FHA. Whatever Roosevelt had himself intended, southern congressmen demanded that blacks receive minimum assistance for private housing. For blacks, money could be used to build 'communities of apartment blocks'--the projects.
A massive amount of urban renewal was conducted by the FHA, especially after WWII. The FHA financed most of the housing in new suburbs, and blacks were
explicitly excluded. The very good quality suburban housing would hold up well and become a source of equity for millions of white families. For blacks, renting of course led to zero equity.
The 1930s scheme remained in force until around 1980, and no compensatory program was ever proposed. Nor were housing policies actually changed very much. The result was the permanent poverty to which most blacks were consigned.
All this was never a secret, but except for a couple of years in the 1980s when redlining (discrimination by banks) was an issue, most journalists didn't cover it. So most people never knew much about the details.
We can discuss race relations until the cows come home (I think we have). Conversation isn't the missing ingredient. What are missing are the means to bring populations who have experienced long-term economic discrimination into prosperity. This is going to be quite difficult to accomplish -- assuming there was a general consensus that we should. What are the barriers?
1. The US is not longer the single dominant economy that it was in 1950. We will probably never experience another boom as long or as intense as the post WWII boom.
2. Income and wealth have become increasingly concentrated among a few percent of the population. The super wealthy are in a position to either promote or scuttle any redistributive justice effort.
3. Building the suburbs was in most respects an ecological disaster and an economic success that can't be repeated (in any practical sense).
4. The structure of the economy has changed hugely since 1945, with large categories of workers being declassed as "unnecessary" thanks to automation, computerization, and shifting production work off-shore. The supply of well-paying low-skill jobs has pretty much disappeared, and even white collar jobs are being affected.
5. Even good education can not guarantee success at this point, because of economic and technical changes. (Education is certainly worth while, but it doesn't have quite same efficacy it once had.)
So, bringing disadvantaged people into meaningful and rewarding employment, decent housing, excellent communities, and so on is going to be extremely difficult to engineer.
What applies to disadvantaged blacks also applies to disadvantaged whites. 1973 was the end of the post-war boom. The 1973 Israeli-Arab war resulted in the Arab oil boycott which sent a shockwave through the world economy. The Arab freeze on oil sales didn't cause the next 40 years of gradual but pretty much continuous economic decline. Several factors drove the decline. The result is that most white working class people have lost most of the economic share they once held. The same is true of the more affluent "middle class" -- people who are better employed, better paid working class people.
I hate the thought that the present economic structure is going to be permanent, with 5% at the top, 20% in the middle, 50% slowly sinking working class, and 25% lumpen proletariat who can't get much poorer. But I suspect that that is what's going to happen.
We should all be talking about it. It's time for revolution. Set up a guillotine in Central Park and let's start liquidating the richest 5%. (Well, they can avoid the guillotine by handing over ALL their wealth.)
