US Politics in a nutshell:

The US forked British Monarchy™ in 1776, but froze the dev branch with Constitution 1.0, so didn't bother to backport any of the subsequent bugfixes and security patches (1831, 1918, 1938, etc.) from the main British branch.

Anyway, you've got a bunch of British Monarchy™ users who instinctively want to tug the forelock but don't have anyone to tug it *at* and it upsets them because homebrew is no good—it takes 700 years of inbreeding to roll your own nobility.
