It's all B.S.
The Democrats place too much faith in the rules of the system (the checks and balances of the three-branch government, the coming of a "blue wave", etc) to even fully utilize their power (let alone bend the rules) to prevent the GOP from continuing to break the rules. The Democrats wouldn't do what that video is saying. (I don't think they'll even have reason to at this point.)
And preppers have been predicting the crash of the U.S. Dollar "any day now" for decades now. (Just like evangelical Christians keep predicting the date of the rapture, but those dates keep just passing uneventfully.)
Take a deep breath, count to ten, and promise yourself you won't believe everything you read on the internet (especially if it seems like they're selling something) and you'll be more discriminating about what sources you consume.
