I'm curious what major part of society people here feel isn't corrupt and dishonest at this point? I'm not confident that I can name any. Politics, government, sports, religion, business... it's all dishonest. A lot of it always has been, maybe all of it.
It's why I observe several communities like this one, of various leanings. It really shines a light on all the deception.
Really, no major one. Even the religious & charitable organizations have been corrupted. There are certainly small isolated groups & individuals that are uncorrupted but that's like finding a needle in a haystack. Considering this, best course is to focus on yourself. Be as good & ethical as you possibly can, be a role model to all those around you so there's at least one uncorruptible person they know.
