Not an expert, but it seems to me that sarcasm is a kind of universal negativity that can be applied to pretty much anything. It's also incredibly vague and ambiguous about whether anything better exists or could exist.

For instance, looking at American news, you could sarcastically say "Go America!" to almost any story (unless it's actually good news, of course). Not only is such sarcasm negative, but it's also very passive.

Sarcasm also strikes me as juvenile. Children complain because they expect a parent will find a solution for them. Juveniles turn to sarcasm because they don't want to ask an adult to solve it, but they don't have a solution either. Then when they grow up, they realize that problems really do need to be solved and no one else will do it, so they need to use more productive communication strategies.
