This is what you own...
This is what you created...
The "40 years of social justice engineering" of which you speak, just happens to coincide with a very hard swing to the right taken by the entire country on the heels of the election of Ronald Reagan, and that is when the right started portraying minorities as "welfare queens", as social programs which helped lift generations of poor inner city minorities out of poverty as "free stuff".
Sadly for you fools, these tired old lines don't work 40 years on when you have generations of middle class black folk getting harassed by the police every time they don't leave the house wearing a suit and tie. And generations of white suburbanites who have been falsely taught to be believe that all black people are dangerous armed criminals who hate white people.
People are sick and tired of telling themselves that police forces shooting and killing 1000 people a year is just fine. Cities paying out "excessive force claims" in excess of $250 million annually is just fine, and that the police state Republicans have created for minorities is necessary for the safety and security of white people.
The pandemic has broken down society into two classes of people: those whose lives matter, and those who are "essential workers" whose lives matter less, but whose work is necessary for the "important people" to survive. If their work is so "essential" to our way of life, why do they pay so little?
This isn't happening in the rest of the first world, where the working class is paid a living wage and has government funded health care, unemployment insurance, and sick leave. All the things American workers don't have.
Most places in the rest of the world do not tolerate what we do. But you are right about policing. It is uneven. The elites want to nationalize the police force. Some departments are much better then others. We will end up with a nationalized corrupted force with the power to stamp out resistance. Real resistance. And they are more worried about fly over country then the urban areas.
