Your sarcasm is appreciated. Repeated standardized testing has proven what is already accepted as fact to me indicating I have no academic potential. This is also verified by years of what I feel meaningless education in the traditional academic institutions.
You brought up a quite interesting point in the last paragraph. How do you assess value? There are ever more people in the world and with the workforce being automated away or outsourced, even the countries that are being outsourced to are outsourcing their labor, how do you assign a number to a person if you even choose to hire them? Education is one of the most inflated industries in the past decade with soaring tuition expenses and on the flip side have the salaries risen at the same rate? If one actually trust the numbers published by the BLS then one is lead to believe that we are bouncing back from the 2007/8 incident. In all actuality, with the industry ever pondering over the hike in interest rate, the global economic situation is rather bleak. We're actually not supposed to be working this much anyways from the advances in modern technology as the forefathers of Economics predicted that we wouldn't be working at all right now.
You are suggesting that in order to achieve some level of "success" in life, one needs to obtain a substantial wealth. As a stepping stone, historically speaking, those with MBAs are able to attain this path to success. How many pyramids do the Pharaohs of the modern day wish to erect after they depart this life? You could be a seven time world Champion in Formula 1 or a famous comedian/actor and then due to a slight fall on a ski trip or a clinical case of depression you are reduced to a vegetable or decide to take your own life. Both embody the qualities that would list them as successful figures in the Western society yet where are they now and what of their wealth?
Not everything can be explained so easily in life. Is this test difficult because I am stupid or is it because I lack the effort to ace a stupid test? There does exist a natural limit, as you have pointed out, for each individual for any activity. This preparation for most is an artificial inflation of their "academic potential" which gives a false feedback in deluding the test taker in believing they have a higher than normal academic potential.
Let me elude to my example of the Marathon once more to further explain my point. Given the answer book/solution all students can figure out the problem. Not all students can figure out the problem without any prior training nor can they figure out
new problems in the same time. In the real world, not all problems have solutions nor are they this straight forward where some simply multiple choice strategies can facilitate not knowing the answer but being correct from elimination. All people can train for Marathons regardless of their age, gender, nationality, or health condition. However, some have died from running them because of pre-existing conditions or some other cause of sudden death. A lot of people run this race and do so consistently until they are injured from over training by running their joints to exhaustion while others can race well into their twilight years. Some are born natural runners with great athletic and aerobic capabilities (born to run), others athletic but born sprinters (Bolt), and lastly some born who cannot run due to some pre-existing conditions. Much like the GMAT, a Marathon is a gauge of the overall fitness of the participant and their endurance abilities. If you know you have a pre-existing condition or you simply have no athletic abilities why would you want to risk death to train for a marathon? Some call this bravery but others call it foolish. Of course, just like the GMAT, there are coaches for Marathons and running clubs (like GMAT club) where people encourage each other to train or whatever. No amount of encouragement or hardwork is going to help a naturally disadvantaged racer to win a race when competing against those with more innate talent.
Those who artificially trained up to 700s go up against kids who spent very little time on getting the same score. Likewise, it is going to be the same arrogant students that can go out and have a life while the students who are just 'normal' struggle with assignments trying to catch up. I've seen this way too much at a top Engineering school and found little meaning in being cannon fodder for those 'talented' individuals to get their good grades. After six years of academic jolly for a BS/MS plus the years prior to that have served as more than sufficient proof that this isn't the right game for me. The only winners here are market makers (tutoring services, etc) , brokerage firms that ate up commission (tuition), and the other individuals (arrogant smart kids) that profited from my academic loses on the bell curve.
Life is a game of attrition and a zero sum game. For every winner out there you have many losers and yet we are lead to believe that we all can be winners. It is full of contradictions and paradoxes unexplained by living the 'normal' life. If you spend your whole life training for a race that you were never intended to run how are you supposed to find out what you are supposed to be good at? How does this test assess business potential or the skills required to succeed in business? is there a direct correlation between networth and the GMAT score of MBA students?
It's better to admit that you don't have what it takes to succeed in certain things than to spend rest of your life validating that assumption. Life is short, why spend it in misery in pursuit of things that only bring more misery? For those who think improving a number is the fix-all for problems in life perhaps getting an 800, 4.0 GPA from a top school, and a 9 figure (USD) annual salary is the way to go. Someone out there is doing it and if you're not first you're last.
