Incompetence, our "leaders" are woefully incompetent. MAGA, GOP and the right are filled with idiots. The Liberal and Neoliberal Democrats at least were a little better at stealing everything from us and delaying progress. They would bury people in culture wars and keep their followers busy with DEI rules. They used legitimate racist issues and then said everything was caused by racism and not that the 1% was just stealing everything.
