This is kind of like saying you don’t read every line of code for the product you ship

The actual situation is that the politicians are paid by outsiders who write the bills which the politician then submits. It's like outsourcing to North Koreans but getting paid by them as well as your actual employer.

I think what you’re missing is that a politician is a face for an organization with staff who do things like write bills.

That’s literally the function of politicians - to personify a group.

Eh, more like don’t actually do your code reviews.

They read the parts they care about very closely, and get a high level overview of the parts they don’t - or rely on relationships that the parts they don’t care about will be filled in reasonably.
