The popularity of the British monarchy in the US is a complete mystery to me. Looking at it objectively, why should we like or support any monarch or monarchy? Its anti-democratic. It’s not merit based. These people did nothing to earn their position—as were just born into it. The ceremonies and events are a drain on state resources. The monarchy as a whole is just the remnant of a system of government that spent hundreds of years dominating and suppressing other forms of government. I really don’t get why they are so popular here.
