The government may not be a business, but that doesn't mean we can't benefit from running it similar to one. For example, managers are people who understand and use MANAGEMENT, not just any random person who happens to make a certain amount of money (like tech people who are promoted to management that don't have the skills or desire to do so).
Also we do a very poor job of connecting talented people to jobs that would fit them well. Younger generation folks join up and then leave in disgust when they find out they hate the work or are never told about advancement or lateral moves they could have made.
Lastly, we waste so much money on stupidity, error, poor contracting, etc that it's no wonder no one supports additional taxes: everyone knows we have enough money and we just misuse it.
I think we need a concerted and continuing effort to find inefficiencies, develop solutions, and implement them.
