Who is "we" in this context?
Black people who live in majority black neighborhoods, cities or states vote for aldermen, mayors, and other representatives at local elections who speak to their concerns. If you want to know what black people want out of the federal government, you meet black people at the local level and see what's important to them.
It's not rocket science. We want the same thing anyone else does in this country because the issues they're suffering with are worse for us. Black people have less access to health care, less access to affordable housing, less access to post secondary education, less access to stable infrastructure, less access to credit to start businesses or buy homes/cars. The way to solve the problem is to give federal funds to local state programs with a proven track record including programs implemented by local non profits. Non profits in your community are filling the gaps left by government by providing meals, medical care, tutoring, child care, homelessness prevention etc. They need more money in their budgets and the fed and state governments can make that happen.
Ja rule isn't going to tell Joe Biden something that he doesn't already know if he's spent more than 30 seconds talking to the head of a local united way chapter or mayor in a black city.
