It's easy for politicians and business leaders to build shiny new things. Politicians get voter approval, business leaders get board approval. Everyone is happy. The ongoing maintenance of these things? Nobody wants to get involved in that - up and down the ranks. Politicians and business leaders don't get the accolades they seek, the rank and file don't get the CV enhancements they seek. So everything slowly falls apart until things get so bad we get to destroy the old and build shiny new. Rinse and repeat ad infinitum. This is the origin of the old adage "things have to get worse before they'll get better."
