I'd throw in:
1) Kowtowing to teachers unions and public school systems, spending 2-3x times more per pupil than we did 50 years ago while black outcomes remain subpar - there's strong support among blacks for charters schools and greater school choice for good reason
2) Minimum wage laws - if we want to talk about structural disadvantages to blacks, here's a law with explicitly racist origins that has persisted far too long...black teenage unemployment was twice that of whites in 2019, but there was no gap in the early parts of the 1900's
3) War on drugs - a failure which has gone on long enough
Among others
