Why Nepal needs to CANCEL Federalism

Nepal adopted Federalism after several long discussion, fight and protests. "Gaun Gaun ma Singha Durbar" was what the politician promised. But even after the completion of first term, Federalism isn't delivering results as it should. People have been calling out Federalism as too expensive, just a way to feed politician and many more. So, does Nepal really need Federalism, or will it even work?
