>The Queen does still have some political power.
Yes she does, but very little.
>I'm certain that the amount of money that tourists bring into the UK because of the Royal Family is far greater than the money we give them.
Not always. Even if I didn't live in Britain, I would still want to visit, just for the political, and traditional ties between the US and the UK. Believe me, the royal family is not the main purpose for people to visit the UK. Most people go for other reasons, but take part in the fanfare, because, you know...it's tradition.
>They often visit other countries to help the relationship between the UK and the rest of the world.
This is true. They do visit other nations for diplomatic purposes. Despite the fact the the role of the monarchy is pretty much relegated to that of a figurehead, royalty still maintain an air of respect, and it is seen as an honour for a host nation to receive a state visit by a monarchy.
