Several states actually started reduced/free higher ed programs during or right after Obama’s presidency.
Cops are actually being held to account in public for being racist or abusive, power-drunk shits. Unlike under Bush, where they were “heroes” who could do no wrong. BLM did a lot to the reputations of law enforcement in the US, and it was a good thing!
Marijuana legalisation/criminal justice reform also started under Obama. Again a good thing.
Race relations? I hardly think that Obama causing racists to come out of the woodwork and act butthurt was his fault.
