These people actually think they’re important. From Caitlin Johnstone at caitlinjohnstone.com:

The weekend’s White House Correspondents’ Dinner saw a gaggle of media celebrities congregate to congratulate one another on what a great job they’ve been doing bravely telling the truth and holding the most powerful government on earth to account. The host, Trevor Noah of The Daily Show, gushed with enthusiasm about how much freedom the press have in America to say things the powerful don’t like.
“As we sit in this room tonight, people, I really hope you all remember what the real purpose of this evening is,” Noah said. “Yes, it’s fun. Yes, we dress nice. Yes, the people eat, they drink, we have fun. But the reason we’re here is to honor and celebrate the fourth estates and what you stand for — what you stand for — an additional check and balance that holds power to account and gives voice to those who otherwise wouldn’t have one.”
