The Crown and it's estate is vastly wealthy.
The Crown and estate generate wealth, they hand all this over to the government in turn for 25% back as "The sovereign Grant"
You will have seen The King proclaim this in his proclamation if you watched it and listened.
Seen as multi billion pound windfarms have been built on The Crown Estate recently you are about to see over the years a "windfall" (pardon the pun) hit the books.
King Charles has specifically asked that this income (from the windfarms) be directed to the people. He has also requested a reduction from the 25% due to the cost of living crisis. Weather they (the government) allow it is another thing.
This proposed £100million pound bill could easily be paid off in a week if they flogged some paintings 🤣
They literally own through inheritance for hundreds of years capital of eye watering billions. They aren't building new palaces, mining new jewels and painting new masterpieces, they have inherited it all.
What are they supposed to do? Sell off their inheritance? Would you?
People can't help the families they are born to, people will always be richer than you. That's life.
