> Eventually, UK citizens lost their faith in the aristocratic system. But they did. I may be kidding myself

To start with, getting fed up with aristocrats would be a revolutionary and progressive thing, not conservative. But it does not seem like there is enough such sentiment in the UK to change things. They still have their royals with veto power, they still have the unelected house of lords with aristocratic, religious and appointed hereditary members and the FPTP system. The house of lords can infinitely send back any bill to the parliament, by the way - which amounts to a total veto power.
