Cynicism is the bastard cousin of skepticism. While optimists look for the silver lining, cynics can't fail to see
the fly in the ointment and true skeptics are somewhere in the middle. Cynicism is an overwhelming trend in internet forums. The most upvoted reactions are usually the more pessimistic (regardless of factuality), and seemingly virtuous attitudes are immediately met with assumptions of bad faith.

Cynicism is tiresome and can very well lead to false conclusions.

This may be unlikely, but paradigms can be improved, governments can adopt better policies, corporations can act for the good of society, billionaires can be virtuous philanthropists, assholes can learn to be nice, and bigots can learn to respect diversity. We should be absolutely skeptical of sudden changes of attitude, but indiscriminate cynicism creates an environment that does not reward positive changes, and I don't think that's in the best interest of a community.

EDIT: I feel I need to clarify that cynicism is not equal to skepticism. Skeptics refrain from conviction in face of insufficient evidence, while cynics assume bad faith even without sufficient evidence. I am not advocating for naïveté, but for healthy skepticism.

I have a friend at the office, who is very dear to me. I don't have many friends, and I've known this person for over five years. But recently they've become increasingly cynical and sometimes outright toxic. Saying things like "our job doesn't matter", "nobody cares", and "you should stop trying to improve things". The company we work for had incompetent managers for the last couple of years, who were ignoring issues and basically making it up as they go. The management was basically purged, and now there are a lot of new people. So I guess it is my friend's way to cope with the situation. But it feels unhealthy, because recently they started lashing out on people, including new people who have done nothing wrong yet.

I am honestly kind of afraid to bring this issue up to them, because (a) I am afraid to lose them and (b) they will probably respond with something along the lines of "you don't know what I've been through", or "eff off", or plain old silence. I feel like they are hurting, but I don't know how to help.

What should I do? Should I do anything at all?
