Right - I'm using the best available data I can find. You seem to prefer ignoring the data we have, with the post-hoc justification that it isn't perfect in every way. Do you do this when the data supports your preconceived notions as well?
As for the "cognitive dissonance", your definition of hardworking is circular:
Hardworking: (adj) industrious, tireless, untiring (characterized by hard work and perseverance)
Industrious: (adj) hardworking, industrious, tireless, untiring (characterized by hard work and perseverance)
In a fact based discussion, one usually needs to construct a more precise definition of colloquial terms. There is no effective procedure for determining whether individual X is hardworking by the dictionary definition, and thus we cannot count the number of hardworking people. I constructed a definition which a) is measurable and b) which roughly agrees with my intuitive notion of what "hardworking" means. If you don't like it, replace "hardworking" with "Category H" in my previous post.
Sorry if my attempts at precision and use of facts interfere with your desire to confuse things and revert back to your preconceived notions.
