It seems like America feels that if they apologize for slavery, they're admitting culpability, and that would mean that they're going to have to break bread for us, like they did the Japanese Americans during WWII, and paying us back would be a HELLUVA lot more than what they had to pay the Japs. Not only would they have to take responsibility for slavery, they'd also have to take responsibility for everything that followed it (Jim Crow, etc.) and its effect on us. They paid the Japs, and gave the Natives casinos and certain federal perks. Truth is, they can't afford to pay us what they owe! They've "acknowledged" that it was wrong, they've never apologized, and they never will. Apologizing is like that loose thread on a sweater. Once you pull it, it could unravel the whole thing. Btw, asking a question doesn't make you an asshole, fam.
Congress has already made an apology for slavery and Jim Crow.
The catch was that the apology was non binding, meaning they don't owe us shit. Just an "oops, my bad" and a slap on the ass.
