What happened in those dense metropolitan cores was bad, and so the good people fled, happened over and over again and people didn't learn.
There's a reason Hong Kong can have extreme population density and low crime, and detroit and any where else filled with Obama's sons is simply a place where even progressives who say things like you do try to flee.
I was a fast cashier as a teenager but its no longer a job for teenagers in many places, its broken people barely there.
The fast check out is far more than 8 machines in half decent areas, maybe double that and I can get out of there in record time.
I'd rather handle it myself than stand in line.
High trust scan and bag won't work in a low trust diverse society, let alone one where some groups are now entitled to theft.
If you want open borders and are foolish enough to add "diversity" you cannot afford generous social safety systems.
People with genetic and cultural ties are more likely to sacrifice for one another, go figure, this has to be explained now to the progressive which is madenning. You cannot have nice things when you turn the social contract into a rental car.
Race matters, its why those nordic countries the left looks at longingly as example were made possible because they were homogenous, something they've been foolishly trying to undermine by following our example. Race matters, in homogenous countries a stranger is more related to their country men than the mixed race child. Why is Japan still functional, again, its homogenous, they are a cohesive people, and yes they do fat shame.

"Asylum seekers and immigrants from Morocco and Horn of Africa costs the Dutch state €475,000-€625,000 per immigrant.
This can't be the best use of resources! Even if you are only interested in using the tax money to help non-Dutch people, you can save a life for ~€5,000." https://twitter.com/jonatanpallesen/status/17425869645769609...
"In the 18-24 age group, immigrants commit 90% of pimping crimes, 56% of **es, and 53% of robberies despite being only a small percentage of the population. The Italian government refuses to release data showing the percentage of these crimes committed specifically by Africans." https://archive.is/20230914033526/https://twitter.com/monito...
High grade human capital for import dried up after ww2, we are no longer importing Einstein, even worse in europe to be sure.
So really your take is self defeating, but much of the progressive lefts antinatalism is which calls into question their entire agenda.
The people you are likely referring to for the chattel excuse history also under perform in country after country where such things were never allowed. Diversity is difference, and difference will lead to persistent disparity.
As studied, and as the logic would follow the elite simply transfer from system to system as performance disparities persist through the generations because of genetics. Through revolutions under different systems tracked family lines out performed others regardless of system. A look at "communist" china.

Furthermore children are likely adapted to be parented by their parents.
The "Three Identical Strangers" documentary on the twin study they buried over likely inconvenient conclusions could only hint at it. The triplet that came to a bad end had a parent very unlike themselves in disposition.
Adopted children also do not gain the full benefit of natural children of good parents.
Recently they found the negative effects of spanking is more related to genetics than the action itself. https://twitter.com/DegenRolf/status/1516070970624249857
In the nurture over nature debate, nurture will only ever continue to lose ground.
Early pc's had separate and very expensive mpeg decode boards just to decode dvd, creative sold a set, the cpu simply couldn't even handle mpeg 2. I know its hard to believe but there was a time when playing back an mp3 was a big ask, all these algorithms could be made long ago, but they would have been impractical fantasy. Only now are we seeing real partial cheated resolution ray tracing in modern high end gaming hardware now which is a good comparison, ray tracing has been with us for a long time, only hardware advancement over decades has made it viable.
It amused me that they claimed 4k uhd h265 is now 10GB for a movie, that's garbage bitrate, they always ask too much of these codecs.
