My bad, I thought that you were saying the country had already tried to provide reparations specifically to descendants of slaves, when in reality just a small handful of smaller jurisdictions and private institutions have attempted anything. But as for your specific examples:
Japanese-Americans interned during WWII.
In what way would you say this "didn't do anything"? Japanese Americans themselves made specific demands and they got a lot (not all) of what they wanted. As a group, Japanese Americans have a lower poverty rate, higher educational attainment, etc than Americans in general. I'm not saying that's because
of the reparations (which were paid out only to a small number of the total population of Japanese Americans, and probably after Japanese Americans as a group were already doing ok), but I don't know what your criteria are for reparations "working" or how those criteria apply to this case. What do you think these reparations were meant to do that they didn't?
Native Americans compensated via the Indian Claims Commission.
This is probably the best analogue, but even so, the scale and structure -- and even the purpose -- of the program are pretty different from what you would probably see with a slavery/Jim Crow/etc reparations program. The ICC was conceived basically as a forum for tribes and other groups to press discrete claims against the government, as a reward for their contributions during WW2. It was not conceived as a broad program of reparations intended to achieve some particular goal, like closing the racial wealth gap between white Americans and indigenous groups, to pick one potential goal that has been suggested for a slavery reparations program. And it wasn't even the kind of "reparations" that many people wanted. They wanted their land back, but the ICC paid out monetary compensation. And all in all, it didn't actually pay out that much monetary compensation -- about $800 million, which is pretty cheap in exchange for taking a whole continent and genociding 90+% of the indigenous inhabitants. If the US tried to pay slavery reparations through a program modeled on the ICC, I agree that it probably wouldn't work very well.
Victims of Chicago police violence.
Victims of the 1923 massacre in Rosewood FL.
Seems a stretch to call either of these something that we tried "as a country." These were both small programs targeted at small groups in specific localities (the Rosewood one only paid out to like ten people). The Chicago one only started a few years ago. Not really sure how you can look at either of these and conclude that a broad national reparations program couldn't possibly do anything for anyone.
Victims of forced sterilizations as part of the Eugenics program.
Here's another one that is highly targeted and has only gotten underway in recent years, so also a weird one from which to try to draw conclusions about what a national reparations program could accomplish.
As for the handing out cash and your argument about rich vs poor ability to manage that money. They say if you can't manage a dollar you can't manage a million. We've already put programs in place like affirmative action and in some cities better access to loans. I think these ideas are honorable but I'm not convinced anything besides some internal actions will ever fix these issues.
Hard to manage a dollar if you've never had one in the first place. The idea that black people don't have any money because they don't know how to manage it is, well, you're gonna hate hearing this, but...racist. And even if it were true that black people can't be trusted with a cash payout because of, well, whatever surely not
racist reason you can think of, that would only speak to the form that reparations should take, not whether they should be paid at all.
Reminds of when Ice Cube went on Bill Maher to call him out for dropping the "N" word. He told Bill Maher that nothing has changed with the police since NWA came out with "Fuck the Police". He says not all cops are bad but we have to call out the bad ones. One could say the same applies to the bad apples within the black community who negatively impact the entire black community. Yet there's a culture of not saying anything and not trying to fix this from within. Just how cops for years protected each other and probably still do. If the police department don't fix themselves from within, no amount of outside rules, regulations or programs will fix the issue. It's easy to say this about police departments but you say this to black people and you're in trouble.
One idea I fully support is getting black people into more small business ownership and they should receive priority on all legal marijuana licensing.
I want to see racism and racial relations fixed, I'm just skeptical about that being a realistic possibility. If that makes me a bad person, fine.
I don't know whether you are a "bad person." I don't think that is a very helpful frame. I think you said some pretty problematic things in that first paragraph of the above quote, and I don't really have the energy to explain what is wrong with it if you don't already understand cuz it isn't anything we haven't already discussed before anyway.
