On Job Requirements

I am a retired corporate executive who spent about 30 years in corporate life. Administration and finance was my background and field of experience. I have an MBA from the University of Georgia, but I never went to school to prepare for a CPA degree. Because I did not have this professional credential, there were some positions during my career that were not open to me, even if I had the knowledge and experience to do the job. Now, let me go to my point.
One of the most vociferous spokesperson (Tancredo) of the right wing Tea Party movement suggested that we should have a literacy test before people are allowed to vote. I found myself in agreement with this man, perhaps for different reasons. He probably wanted to use this pre-requisite as a tool to keep some undesirable elements in society (in his view) from voting.
A test of qualifications is required for any job, except for the job to be a member of Congress. That lack of testing for our honorable representatives results in the shameful and unbelievable state of affairs observed when our representatives in Washington discuss and give opinions on matters about which they are ignorant. We have people in congress that never took a basic accounting, economics, or finance course. Even so, they are required to analyze, give opinions, and contribute to the creation of laws in an effort to keep our society from going bankrupt. We remain paralyzed going from crisis to crisis, because our honorable representatives are unprepared to understand what is happening in the world they are supposed to govern. Why do we not require our members of Congress to pass a technical literacy test? Why? Why not? If we did, we would be assured that they have minimal qualifications to hold their jobs.
