slightly related: bees are in decline and worth hundreds of millions to UK economy being pollinators for major exports apples/cider. hence the need for more protected and greener spaces. I read somewhere that bees provide more money for the UK than the royal family
No, not even true. The Government makes a profit on the Crown Estates, the Civil List is entirely covered - and MUCH less than say the French pay on their President. And we haven't even started on revenues generated from tourism, etc.
The Crown Estates would be public land, and without the royal family we could open several large buildings as museums — and charge entry to tourists if we want to profit.
We'd also be free of some racists, a sex abuser, and a meddling old man, who claim to represent the people of a democracy but have never stood for election.
The crown estates are not owned by the public, they are owned by the royal family. To transfer them to public would need the government to give the royal family a massive pay out.
