Establishment Democrats like focusing on identity politics because it takes the focus off of economic policy.
Like center-right economic policies??? Florida $15 minimum wage blew way past Biden vote count. I do think there is sometimes self-interest involve, however, where that is the case, especially if there's a directly identifiable effect e.g. CA Uber/Lyft proposition that passed. Even liberals want their serfs. Liberals, not just conservatives, will also try to retain advantages if pols implement them and then it's very difficult to take away e.g. Proposition 13 -- lots do not want to give up not having to pay a fair share.
CA had a proposition for preferential treatment in government jobs for minorities. That's not inclusive. That's setting up privileges.
Democrats try to make the issue all about black people. Common sense does not prevail here. Black people commit significantly more violent crime. Black people disproportionately kill more cops. You can expect a disproportionate amount of black people to get shot.
