All of the colonizable places to settle are taken.
The window period to settle a place, “remove” the indigenous population by force and establish a government of people who come from the same background as you has long expired. No more Americas. No more Australias.
From now on, you will be a guest who has to integrate yourself.
But you ended up here the wrong way? Your ancestors were brought as slaves, and their earlier descendants attained belated citizenship, and then their descendants fought for the ability to integrate into employment and voting, and now you are tired of fighting for respect from an inherently-classist criminal justice system steeped in the same system which preserved slavery? You want out of this country and its status quo?
Well, at least if you leave this country for another, you’ll be doing so on your own terms. It won’t be a panacea, and you can’t expect to not face racism as a guest.
But maybe, as an immigrant to another country, the art of respectability politics might save you.
