The idea of a distinctive, unifying, risk-taking American DNA might also help to explain our most persistent and painful racial divide – between the progeny of every immigrant nationality that chose to come here, and the one significant group that exercised no choice in making their journey to the U.S. Nothing in the horrific ordeal of African slaves, seized from their homes against their will, reflected a genetic predisposition to risk-taking, or any sort of self-selection based on personality traits. Among contemporary African-Americans, however, this very different historical background exerts a less decisive influence, because of vast waves of post-slavery black immigration. Some three million black immigrants from Africa and the Caribbean arrived since 1980 alone and in big cities like New York, Boston and Miami close to half of the African-American population consists of immigrants, their children or grandchildren. The entrepreneurial energy of these newcomer communities indicates that their members display the same adventurous instincts associated with American DNA.
If Whybrow, Gartner and other analysts are right about the role of inherited traits and tendencies in shaping our national character then the insight carries crucial political implications. Senators Obama, Clinton and other leaders who seek to enlarge the scope of government face more formidable obstacles than they realize. Their desire to impose a European-style welfare state and a command-and-control economy not only contradicts our proudest political and economic traditions, but the new revelations about American DNA suggest that such ill-starred schemes may go against our very nature.
