If society is doomed, you and I aren't going to save it. Authoritarianism is too popular. People who don't buy into- and use- political "authority" are at a disadvantage because of this. The best you can do in this case is to resolve to be part of, or encouragement for, The Remnant.
If society isn't doomed; if the problems will work themselves out, then maybe you and I can be a small part of that. Help spread ideas that will help others solve the problems. Keep poking holes in statism's lies. Keep pointing out the inconsistencies and hypocrisy. Keep finding and creating alternatives.
Keep yourself on course. Do right. Avoid doing things that make things worse. Maybe you'll inspire others to do the same, and if society isn't doomed after all, perhaps your legacy will be to be a part of what keeps it from collapsing.
