Yeah, but it could also fix some things regarding racism, sexism, ableism, trans issues, immigration, geographic disadvantages etc. Maybe climate change?
Optimistic of you to think people wouldn't use it as an excuse to be even MORE discriminatory. There would be Ultra-Whites who could claim they were never non-white in the past X years, with seniority by how far back they can trace their reincarnated whiteness. And of course there would be new religions claiming that if you follow them you'll be reincarnated into the race/environment of your choice.
Odds are you aren't going to be reincarnated as a white person though. Seems like they would cut the shit out the first time they are reincarnated as something different.
That's what the basis of reincarnation is about though.... karma. You do good deeds, your karma level goes up, you get a better reincarnated life in the future. Likewise, the opposite is true as well.
Karma is an aspect of the Hindu and Buddhist reincarnation beliefs. They do not have sole ownership of the concept of reincarnation.
If they had said "What if Hinduism is right and reincarnation is real?" then that would be a different scenario. They only put forth that the concept of reincarnation was real.
Ah I see what you mean now. Eh, regardless I'm sure the universe would have some sort of similar karmic system in place to prevent thatt suicidal loop hole.
