Not better, but it's what we have and it works, it's no more or less expensive than any other systems. An hereditary system simply does away with all the farting about every four or five or ten years to get a new HoS installed. Qualifications aren't needed when the post is a purely ceremonial one. It's just a matter of convenience.

Nor is the income from Crown Estates rightly public money. It is rightly the Crowns' money and, legally speaking, the King as sole representative of the Crown would be within his rights to take it all and do as he pleases with it. Instead he takes less than a quarter (£86M out of £442M is less than 25%) of it in the Sovereign Grant and the rest goes to the Government. Fuck knows what that shower spend it on!

Really, abolition of the monarchy in the name of either democracy or modenrity would be purely performative at best. Frankly, to see some superannuated soccer player or witless reality 'star' laying a wreath at the Cenotaph would be much more of a condemnation and a mockery of democracy and modernity than the current system could ever be. For a politician to do so would really be (really is) hyporcisy. But I suppose you believe that Remembrance Day should be abolished and the Cenotaph thrown into the Thames?
