I will say, rattumb migrationists have the virtue to believe that gentrification, too, is a necessary tradeoff in favor of freedom of movement/commerce, and thus are more ideologically consistent than a number of left politicals.

And therefore we don’t get the double-bind where the ethnic majority either leaving or entering the city is considered problematic in both directions at once, acting as a cover for what are actually class concerns.  (And also rattumb has greater awareness of what might actually sort out housing prices.)
