If nothing else, our economy would suffer very very badly if the monarchy was "removed".
I happen to like the whole thing anyway; heritage, history etc etc etc
as to the point somebody made about how many were out of work and how much wedding cost; there's a consistent 80% support for the royals here
(from all walks of life and income levels), and there would be a HUGE number of job losses should we become republicans.
the wedding was paid for by the Queen; the security (admittedly very costly) was covered by the taxpayer.
