If we abolish the monarchy, what do we have instead?
Bearing in mind we only have an inkling of the corruption and nepotism going on behind closed doors in government.... Look at the US - the current investigation with Trump and the FBI shows how dangerous it is to have an elected official who's unsuited but popular.
There are criticisms of the royal family, but I think in general people don't really understand what the monarch does. Recent documentaries on the queen have really been eye-opening on just unbelievably stressful the role is, and how enormous the responsibilities are.
I think Charles and William will be more involved than the queen, while still politically neutral, as required. I also think they'll slim the monarchy down. Charles especially is quite good at reading the room of public opinion.
If the objection is to their inherited wealth - then what about lords and ladies? Other nobility? Unless people are proposing a switch to Communism, there's always going to be those with more.
In the absence of anything better, I think the monarchy should continue for Charles and William at least. We can then review and see if it's still fit for purpose.
So - keep.
