The only thing they represent is tradition and history. To blame them for any sort of social mobility issues is inept and simply a distraction from any genuine solution to economic issues.
The ignorant rantings of moaners aside, I saw a happy country when I was out jogging on Friday. Flags, bunting, parties and good nature. Not BECAUSE we have a royal family, that's just silly, but it is all part of an embodiment of something significant and useful which meant people felt like putting the effort in that day.
They don't cost us a darn thing- quite the reverse. If we didn't have them, we'd still need some sort of head of state, which would still include public holidays and security costs, only this time accompanied with typical bloated government bureaucracy.
Talk of privilege is stupid, as the Royal Family is basically obliged to support the country- they have a role to fulfil. You can dislike their wealth, but then you have MUCH bigger problems than the royals to worry about.
If you think getting rid of them solves any sort of issue at all, you are mistaken. All you would achieve is to diminish a part of this nation. Again, really these feelings of yours are very petty indeed and attitudes like yours are a much bigger problem than the monarchy could ever be. Decades on, you'll still be left with social mobility issues and then who will you be able to blame? Or will you then finally realise that's an economic issue, not one related to mere tradition.
