The problem of this world is not that we cannot solve the problems of the world. We can actually solve all problems very easily. However, many people do not want to solve most problems at all because they do not usually see things as a problem. For example the current problem of racism. Racism is not a problem from the racist's point of view, but only a problem that the victims have. He doesn't even understand what people are upset about.
So you have to bring the problem closer to these people. That is why a racist has to experience disadvantages for being a racist. Don't be nice to them. Don't do business with them. They will cry and complain. But they only experience what colored people have been experiencing for a long time.
