The government should be hiring the brightest and best with the best work ethic they can find to fill all government jobs. Immodestly perhaps, many of my former employers hired two or more people to replace me when I left because I prided myself on figuring out how to work fast, efficiently, effectively and do the necessary work very well in less time so I could take on additional work. Making myself more valuable to my employer almost always netted me higher pay and sometimes better opportunities and benefits.
I suspect people like that are legion. And we need them as public servants at all levels of government.
People actually doing their jobs, doing them effective, efficiently, competently will do ten times the work that those who work only as hard or much as they have to to keep from being fired. If you have a work force of the latter, RIFS are the only way to go.
But no business can operation effectively and efficiently for long if you are paying more people than you need to get the job(s) done. Some say you can't run the government like a business. I say that ONLY government run like a good business will be efficient effective, competent.
