This is because this is serialised comic books, and Marvel isn't going to accidentally discover the solution to racism or oppression, as well as the fact they know they can't change the niche X-men fill in the Marvel universe with Claremont. Allowing Xavier's dream to come true will destroy the relevancy of X-men as a popular franchise.
The loop continues with Hickman, all he did was put them on another island, Krakoa is Utopia 2.0. The X-men transferred from being hard and feared in a mansion to being hated and feared on an island. Hickman's simply taking a new direction with old ideas.
Again, this is mainstream super-hero comic books. Status quo's are modified they don't truly end.
That's just the status quo in X-line, bigots will be bigots and Krakoa isn't helping sooth fears.Edit: Plus humans are even more paranoid about the drug system with Kraoka to they point they were killing humans supporting mutants in X Force.
