The unfortunate reality of the breakdown in trust is because the institutions are behaving in a way that would reinforce this. It is easy to look at the extremes like Qanon, but even if you look beyond the surface on any institution in this country, it is really hard to be positive or hopeful about anything. For example it is hard to trust in the Supreme Court once you notice that judges (on both side of the political spectrum) have been accepting favors from Billionaires, legally, but unethically. Could you realistically think these judges could rule fairly in cases that involve their benefactors? This was once the highest trusted institution in the country, now think about the ones that weren't that trusted to begin with.
