A question for the UK folks

I have at this point relegated Brexit to the large pile of "I don't understand this and I don't need to" along with oh idk Nigerian politics and inorganic chemistry. I know they exist, I have a vague understanding of how they work, but gods please don't ask me to explain anything.

Basically, I don't see how me knowing about it is going to make the world better enough to be worth the energy.

If I am in fact wrong about this and there is something useful about me, as a US citizen, understanding this godforsaken mess, someone should let me know so I can schedule some time for screaming...
