I agree that the government wastes money like Michael Moore at an all you can eat buffet but things really could be far more efficient without even approaching the efficiency of private industry. One novel approach would be to require government workeers to actually WORK!
Doing what? You don't want government workers working at doing what they are assigned to do. Because of the incompetence of the political management most of what people do is manage process rather than outcome. If you don't know what you want done, any process will do it, and the inside the beltway types argue endlessly over how to adjust the process to ensure that the process can't be criticized by the voters.
Noting useful gets done.
This is why Trump is different. It's like the Wollman Ice Skating Rink story. Do you want a working ice-skating rink or do you want a process to ensure that each step of the process is executed according to the process regardless of what it is you want? Inside the Beltway we want not justice but procedural justice.
The taxpayer cannot afford it.
