You would have change, their whole lieberal believe system that won't simply work.
I don't like the defeatist attitude, but we won't change anything, the biggest changes we bring is through our own lives, live an exiting live, search for you feelings to find your passion, get good at it, get involved politically, be aware of the problems that roam our societies, but don't strae too long into the abyss, and with every thread you read every hour you gaze into the abyss, and it's stare gonna poison your mind, corrupt your soul, take away every energy that's left, that you could bring up for activism in your life and for those around you.
The west has become weak, and were just as strong as our weakest parts, and those are liberals, changes that would need to be done would be a return to a more archaic cultural state, a strong religion, fortified gender roles, strong moral code, and that won't simply happen, except for there would be really a (new) christian prophet that would come into this world, and call out the pope and it's followers, for what their are corrupted spectres.
We became secular and there was nothing that came close to christianity's glory, we tried it with science, wasn't satisfying, we tried it with dictorship wasn't satisfying, we tried it with open love wasn't satisfying, and now we are her in this mix of moral relativism and hardcore individualism.
Survival of the fittest, the one surivives with best but least adaptions.
Don't forget your morals, don't forget your virtues, enjoy yourselvs, achieve your goals, but never get stuck in the swamp of degeneracy, for their is no fullfilment nor beauty there.
I spent so many years arguing here, getting soaked in this impotent rage, becoming bitter, seeing nothing but degeneracy, that I really forget how to enjoy life. Don't lift the weight of a whole society on your shoulders, you just will get crushed, and for those that you are carrying this weight, couldn't careless about it.
