I don’t agree that “burn it all down” is the right solution, especially if we’re hypothetically in agreement that the end goal is the maximization of happiness for the highest number of people. Going through that transition will be worse than what we have now for most, and there’s no guarantee that a more equitable society is built in the ashes of this one.
It has always been this way for thousands of years. Democracy changed the rules a bit, but it’s always been a battle between the meek and poor vs rich and powerful.
