I am always amused at people who cling to the idea that career politicians are "your friend" and that they "care about you". I guess it is the type of idolatry that replaced religion as society becomes more secular.
Power doesn't corrupt, power attracts the corruptible, the narcissists, the sociopath. People how really care and want to change the world for the better don't enter politics. They volunteer, they become activists, they found NGOs and work at the grassroots level to change the world for the better. Biden is as much of a racketeer as Trump.
