I chalk that alongside Reed Richards, T'Challa and Iron Man being a-holes who don't put their inventions on the market, or Thor and Asgardians not curing hunger by ending drought for good.
It's not really an issue that is meant to be thought of too deeply. Ultimately the Shared Universe was never concieved to tell a story by itself. It was always a patchwork canvas meant to sell all Marvel titles and trick people into reading comics they don't care for. It's a carny trick.
At its core, the story of the X-men and mutants are best read when self-contained using the rest of the MU as a springboard for their stories, and vice-versa.
Well Magneto back in the Octopusheim Saga and in God Love Man Kills made it clear that his long term goal after mutant uplfiftment was to transform the world and end poverty and hunger.
And Emma Frost in Marauders forced a bunch of bigots to not only never harm mutants, but also not to harm LGBTQ people as well.
