The problem of all evil comes from people not loving God above all things, and not loving their neighbors as themselves. People are so complex inside, that they can't hold more that a few things in their minds at one time. That is why the Ten Commandments are important. These Commandments are precise and concise enough that anybody can understand them. They are basic enough that they are the groundwork for all other basic laws. They are few enough that we can hold them in our minds constantly. Even if we don't love anyone else, obeying the Ten Commandments mechanically will give us good prosperity, if we do it as a country, from the top down.
