Everything is America is about race
People facing racial discrimination can and have overcome it, throughout our history.
People hold out willing non-white immigrants succeeding as proof there is no significant racial discrimination. But this ignores a large selection bias. People who voluntarily immigrate almost always have a great deal of drive and often some resources. Most of them would have been more successful then average if they had stayed in their home country.
And yes, don't underestimate how such maneuvers are very indirect means of white flight. African Americans could only (legally) own a home in much of the US for 50 years. At the very best, that is 2 generations of wealth to accrue, which puts that demographic a good century behind what potentially could have been economically.
So 58/59 years if we want an exact date. But a law passed de jure doesn't mean everyone throws their hands up and willingly complies, so the sand will still be shakey for a good decade.
Of course, YMMV per state, so it's not like the Midwest or west coast had the same level of discrimination as the deep south. But that's the line that this policy became federal.
Notwithstanding that they were examples of extra-legal discrimination (in the sense of not being direct legal prohibitions), racial covenants and red lining also didn't just effect black Americans, though nationwide they were disproportionately impacted. I only point that out because most people would say it was incongruous to claim Jews or Polish or Asians were legally prohibited from owning land in many areas.
I think it's an important distinction because there are vestiges of redlining that persist today. First time homeowner mortgage subsidies, the first major stepping stone for building wealth for most people, effectively exclude many kinds of multiunit housing, such as condos and, IIRC until recently, attached housing like duplexes. This disproportionately impacts prospective urban black homeowners, and quite deliberately. Likewise, IIUC prefabbed homes or similar are excluded, which disproportionately impacts poor rural whites and blacks alike. There are legitimate concerns behind those restrictions, such as developer and rental fraud, just as nominally there were legitimate concerns behind redlining, namely sustainability of property valuations. Though in all these cases it's obvious the reason they persist(ed) as-is is for largely discriminatory reasons, as the legitimate substance of the concerns could be addressed. At the same time, we wouldn't say they legally prohibit ownership; if you're wealthy enough they're no impediment at all, just like redlining and covenants were no impediment if you were wealthy enough (racial covenants could be overcome by just buying up all the adjacent property so there was no other property owner to enforce the covenant; the government couldn't by itself enforce such covenants, only adjoining property owner "beneficiaries").
Perhaps counterintuitively, black letter property law was one of the legal areas most resilient to both racial and sex discrimination. The 1800s saw some regression, but that didn't last long, often because courts themselves couldn't tolerate the illogic. People criticize it, but property is indeed sacrosanct to American legal and political culture, and it was very difficult to carve out exceptions that permitted blacks and women to be excluded without threatening the underlying principles of the system that secured owners' rights. That's why prejudiced treatment tended to come in the form of private, regulatory, or extra-legal discrimination, which arguably persists today in the form of restrictive zoning and related development policies which not coincidentally are impediments to free & clear property ownership, just enough to be tolerable to the well-off while disproportionately impacting the real targets.
They literally wanted to kill northerners for daring to make them equal to black people.
Still do.
Not to mention how often people misinterpret a survey and add their own bias to the results.
Fixed that for you
It's a bit of a chicken and egg situation. At least when someone looks at someone who "looks like them" but is poorer, they see "potential" (there's a name for this effect, but I forget). But the end goal is getting theirs first and foremost.
At lower levels you have the “labor aristocracy” effect, which gives the more well-off workers a material stake in racism. And this division is useful to prevent organization.
