Say you’re in that top 0.01 percent—or even the top 50 percent (in income.) Would you want to admit happenstance as a benefactor? Wouldn’t you rather believe that you earned your wealth, that you truly deserve it? Wouldn’t you like to think that any resources you inherited are rightfully yours, as the descendant of fundamentally exceptional people? Of course you would. New research indicates that in order to justify your lifestyle, you might even adjust your ideas about the power of genes. The lower classes are not merely unfortunate, according to the upper classes; they are genetically inferior.That's an extract from an article Social Darwinism Isn’t Dead: Rich people think they really are different from you and me. By Matthew Hutson published in Slate.
Later in the article he adds:
"the few studies on the subject estimate that income, educational attainment, and occupational status are perhaps at least 10 percent genetic (and maybe much more). It makes sense that talent and drive, some portion of which are related to genetic variation, contribute to success. But that’s a far cry from saying “It is possible to determine one’s social class by examining his or her genes.” Such a statement ignores the role of wealth inheritance, the social connections one shares with one’s parents, or the educational opportunities family money can buy—not to mention strokes of good or bad luck (that are not tied to karma)."
What do you think? In your case do you attribute your success to genes, the environment in which you were brought up, luck, something else?
