You are correct. I was recently bitching to my British wife about the parasitic Royals and how unfair it is that they live large at the taxpayers' expense. My wife, an East Ender and certainly no Royalist, informed me that the amount of jobs created and money flowing into the British economy because of the Royals is far in excess of what it costs to keep useless inbreds like Charles living in splendor.
After our discussion I did a bit of research on the subject and yep, she is correct.
