Government wastes money. Some of that is unavoidable. A degree of wastage is implicit in every human endeavor. Efficiency is essential, but it cannot become an obsession in any human enterprise whose goal is the betterment of society.
So much to the chagrin of businesspeople like me, you cannot run a government like a business.
That does not mean, however, that you cannot or should not hold individuals and institutions to account. Every dollar spent in the public interest needs to be assessed as to its benefit and its opportunity cost.
