I think at some point we have to stop worrying about the systems and instead focus on what we can do as individuals, how we as individuals can think, behave, and influence others in order to build the type of world we want. We don't have to understand the laws of the universe, we just have to understand who we are, what we want, and what we permit ourselves to go along with and what we will not. If we require some rule to live by, it should be "Do not participate in evil". We all fall short of that, but it is a good to which we should aspire.
