Why do we still have a monarchy?

I agree. Monarchy is outdated. They serve no purpose anymore, except cost the taxpayers millions, when those same taxpayers are struggling to put food on their tables and paying their mortgages. Royals are nothing but parasites on society. Now if they still marched ahead of their troops into wars, like they did back in the olden days, that would be a different thing altogether. But if they still did that, there would be fewer wars. Can you imagine QEII, with Corgis and Ladies-in-waiting in tow, leading her troops into Afganistan? I think not.
