An Elected Head of State is democracy.
It's good Queen can still ride at her age well she has had the best of everything in the land.
Monarchy, on the other hand, precludes equality even as a pretense. There is nothing remotely egalitarian about a system that guarantees, by law, that one family will receive taxpayer-funded grants, literal palaces in which to live, special protections from criminal justice, barely disguised political influence, and the deference of elected politicians. The whole point is that some people are born different—and better—than others. This is a repugnant doctrine.
The state-sponsored extravagance of royalty would be bad enough if members of the Royal Family could be trusted to set a serene example for “ordinary” people to follow. It is made much worse by the fact that, in reality, the royals behave badly. As the great constitutional theorist Walter Bagehot once wrote, “a constitutional prince is the man who is most tempted to pleasure, and the least forced to business.” After all, an idle mind is the devil’s playground—and members of the Royal Family are idle as an occupation.
Prince Charles’s private organisation, the Duchy of Cornwall, is exempt from corporation and capital gains tax, the 18 royals officially classed as “working” each cost the taxpayer an average of £19m a year.
