Looking at the state of racial relations in 1922 and how they changed in the 100 years since then, I sort-of doubt that the situation of 2122 will be anywhere close to today. Someone will probably oppress someone else, but the overall balance of power and ideas will be totally different than today.
In the Western context, that's probable. But no matter where you look, some groups will still lag in a bunch of metrics, xenophobia and racism will still exist in some form and will still be holding them back. That's always been the case and they certainly won't be solved with the two suggestions above.
