Preface: I'm British.
It's very trendy to hate on the monarchy, rationally it makes sense but if we look at the numbers they bring in more money to the country than they take out, Elizabeth evokes a sort of stability in our politics and it's not certain how those affects are felt.
To take the words from Stephen Fry: "It is rational to assume that countries without a constitutional monarchy are freeer, however, the countries which are freeest are Denmark, Norway, Sweden- and they have a monarchy."
