Andre, the best that can be said for your argument is that you know your way around a thesaurus. You’re not actually saying anything substantial between your adjectives.
Most Objectivists are fully aware of the intellectual leftist disdain for the “ordinary man.” It’s evident in their beloved post-modern art and philosophy that they have no respect for the mind; it’s evident in their politics that they do respect or trust man’s efficacy. The leftist misanthropy you ascribe to doesn’t take a particularly fine mind to understand. It has been thought about “clearly” … and rejected. A deep-thinking mind finds virtue in the “ordinary,” hard-working, “middle” American in spite of the cultural left’s pretentious and unwarranted elitism.
You make a case for the “struggling artist” and “struggling intellectual.” I put it to you that, today, the standards in art and the standards in intellectualism are so low, that it’s only right that the “ordinary man” (and Objectivist) is suspicious of them. The beauty of business is that there still remains an objective standard for success (contemporary “management studies” courses, notwithstanding): profit. As a consequence, while everyone here agrees that wealth does not prove virtue or vice, it’s a fair generalization to say that a person who has created wealth is more likely to have applied himself, identified and integrated reality, set goals, achieved them, dealt with the world honestly, etc. And as wealth creation, in general, requires this, the poor person is less likely to undertake these, and is more likely to sit in his cheap apartment, wring his hands, and wonder why his half-baked ideas, or meaningless daubs, go unappreciated.
The original quote was, “Wealth is the product of man's capacity to think.” It really is uncontroversial. And while we can’t say that wealth proves virtue or vice, we can say that if you have obtained wealth, it follows you must have applied some degree of thought, planning, goal-orientation, focus, productivity, identification of opportunities for trade, etc. If you refuse to apply thought and focus, you will not create wealth.
