Many millenials are rejecting traditional status symbols like diamonds that prove wealth, but still pursuing symbols of moral superiority instead of actually helping, in effect diluting the real cause and invalidating sincere efforts.

Both cases are showoffs to say "look how much better I am than you" 

Don't do either.

We are also often characterized my anxiety and insecurity about appearances, perhaps because of being bombarded by media. However, it holds individuals back the same way traditional status symbols may have in the past.

It's often coming from the right place, wanting to be good. Don't just try to look morally upright, be morally upright.
