When you hear a politician running for office proclaim that “government can do no good,” think of him or her as someone applying for a job, because that’s exactly what he or she is doing, and think of yourself as a prospective employer interviewing the candidate for a job in your company, because that’s precisely who you are.
In the course of a job interview:
Would a doctor get hired by a hospital if he said, “Medicine can do no good?” Would a lawyer get hired by a company or a law firm if he said, “The law can do no good?” Would a teacher be hired if he said, “Education can do no good?”
