As for the royals bringing in tourists, this old chestnut, routinely trotted out for decades, has no substance behind it. Not one royal attraction comes in the top ten list of visitor attractions. See visitbritainshop.com for that. You can't show that any tourist coming to the UK wouldn't come here but for the royals. It's pure guesswork. You can make the assertion, I can make the opposite assertion, and we're firmly in flying spaghetti monster territory. I have nothing against anyone holding the deluded view that the royals are a "good thing", but, if you really want to bother making points in favour, at least make sure they are not groundless.
