I fail to understand why public services get shut down because they're 'not profitable'. I don't want my government to be 'profitable', I want it to provide services for the greater good of 'the people', of which I am occasionally a member. Police and fire departments don't get shut down because their EPS was well below guidance, and schools aren't closed because they don't have a clear revenue picture for the next quarter. Congress has been going for over two hundred years and they've never once been in the black. Yet libraries, parks, and public transit should all be 'profitable'? I'm confused.
