So the NSA does not hire college graduates?
IIRC the British monarchy brings in more revenue than it costs. Those most critical of the monarchy put the annual cost of maintaining it at 400 million GBP (more conservative figures peg that as much lower), but the royal family generates 500 million GBP / year in tourism revenue. I'm sure one can poke holes in this argument, but based on these two figures alone, it sounds like the monarchy is worth it.
From the citation:
The British tourism agency has reported that the royal family generates close to 500 million pounds, or about $767 million, every year in tourism revenue, drawing visitors to historic royal sites like the Tower of London, Windsor Castle, and Buckingham Palace. The country's tourism agency says that of the 30 million foreign visitors who came to Britain in 2010, 5.8 million visited a castle .
So if there were no Queen but some actors dressed up like Henry the 8th, people would stop coming to see the castles? I don't buy that. They come to see the historical sites, not to have tea with the Queen.
take your pick and sign up.
