To be honest, the title of this piece feels as pretentious as the original MAGA moniker. The implication that there was some time when America was amazing or wholesome relative to today is corrupt at its core. If we are to be totally honest, the pursuit of goodness or greatness takes ongoing effort, and frankly such a pursuit by a single nation will always be lacking if we don't partner with the rest of the world.
Nevertheless, our nation has some particular challenges in front of us. Greatness of a nation is meaningless if we aren't pursuing goals that are good. Here is my shortlist of good things we as individuals, communities and civilization ought to be pursuing.
Information reliability. Sadly the idea that everyone has a right to ones (peacefully expressed) opinion has become equated with those opinions being equally valid. Religious, new age, and grand conspiracy magical thinking has degraded the reliability of information available on social media especially. Humankind depends on reliable information to inform our policy and decision making. Scientific method, fact-checking algorithms, and individual questioning (with evidence to back it up) can begin us down a path of better information exchange.
