I agree. Just the fact that the couple is married makes African American very unlikely.
Lets not take it to that level, but they odds do run at least by majority in that direction.But whose fault is that? LBJ and his Great Society program which subverted the position of lower status men.
LBJ promised a Great Society, when what he was aiming to deliver was a great (or at least a gigantic) government. People have been seduced by the failure to make the distinction between society and government for a long time:
SOME writers have so confounded society with government, as to leave little or no distinction between them; whereas they are not only different, but have different origins. Society is produced by our wants, and government by our wickedness; the former promotes our happiness POSITIVELY by uniting our affections, the latter NEGATIVELY by restraining our vices. The one encourages intercourse, the other creates distinctions. The first is a patron, the last a punisher.Far from producing a great society, LBJs program stopped the progress of black America in its tracks.Society in every state is a blessing, but Government, even in its best state, is but a necessary evil . . . - Thomas Paine, Common Sense (1776)
Black America would have done far better to have smelled a rat and rejected it. But then,
The natural disposition is always to believe. It is acquired wisdom and experience only that teach incredulity, and they very seldom teach it enough. The wisest and most cautious of us all frequently gives credit to stories which he himself is afterwards both ashamed and astonished that he could possibly think of believing. - Adam Smith, Theory of Moral Sentiments (1759)
