Most plausible/likely TEOTWAWKI doom this year?

Pretty much what the title says. I've been trying to pinpoint what will bring about the demise of society at least in America. I figure it will be some economic factor such as a default, no unemployment checks, shot that will rile up the masses and fuck things up. I don't claim to have any idea what that will be, but I feel like it could easily come about this year or next the way things are going.

I am just curious to others opinions on what will bring the doom for sure this year. Thanks!
