re: #183 wheat-dogg
I don’t really know how the royal family makes money other than salaries from their other occupations (in Harry’s case the military.) The duchies apparently are not really at the discretion of the royal family, though of course they have the privilege of using their lands for their own pleasure.
IOW, I don’t think Charles can take, say, a few million dollars from his duchy and invest in something else. It’s ownership only in the sense of exclusive use.
