1. You support politicians who prioritize funding PUBLIC EDUCATION. Keyword public. Schools across this country have been on life support the past 3 years and none are in a worst shape than public schools in low income areas.
2. If you want to be hands on you can volunteer your time at Boy and Girls clubs or other youth programs. I do it and I suggest others too as well if you really feel strongly about it.
3. Be a positive example and upstanding citizen in your own life. Raise your kids to do the same, be an involved parent, go to PTA meetings, School Board meetings, etc.
On a personal level that is all ONE person can really do. This is the real "accountability" not the one dunce king likes to talk about. White people in this country have had a 200+ year headstart to build generational wealth, passing down land, money, and resources to their children. Black people have not, and the starting point for progress has and always will be education (No it doesn't just mean pointless degrees the trades apply as well).
Y'all want to know why public schools are so bad? Because white people don't send their kids to them, and if they do it's usually 1 or 2 schools in a district they attend. Public schools get funding from tax payers dollars. So if a school is in a place in which the vast majority of the community is living at or below the poverty line the school will reflect that as well. The schools in better areas usually offer supplements to teachers, so the best teachers go to the areas with the most privileged kids, to get the most money.
