Kansas is broke – but you wouldn’t guess it looking at its shining state capitol in Topeka. The imposing limestone monument, crowned by a shiny copper dome and limned with John Steuart Curry’s luminous murals, has just undergone a $325m facelift. What’s happening inside the state house is a lot less pretty, and may well foreshadow the far uglier battle looming over the future of taxation in the United States. In 2012, Kansas did what Donald Trump wants to do: it introduced huge tax cuts to try to boost growth. Today, the state is out of money – and residents are angry.
