Besides national politics, we could be involved in local decisions. Besides having no time to choose national leaders wisely, much of the national government operates in secrecy, and much of the local governments exclude many people especially when someone is making an enormous investment. Everyone has time to learn a little about current events or history, but why a lot don't do it may be for several reasons like not wanting to be boring, not wanting to be controversial, or not believing one can make a difference.
