Whoever researched this article at the WTS goofed. They should have look further back in their own articles:

"What Kind of Man Beats His Wife?
Regarding home violence, certain stereotypes come to many a mind. Persons often picture a “blue-collar worker”—perhaps a truck driver, ditchdigger or garbage man—who stops off at the local bar, “tanks up” on beer and staggers home ready to fight. There are many like that, as we saw earlier in Connie’s and Gloria’s cases.
But if you think that family violence is confined mainly to such persons, you are mistaken. “Family violence,” states the column “Intelligence Report,” “cuts across race, class, and background. It is widespread and occurs as often among the upper middle class as among the lower.” (Parade, October 16, 1977, p. 18)
Wife Beating: The Silent Crisis points out:
“Those who work with battered women report victims among the wives of physicians, lawyers, college professors, and even clergymen. In Dr. Gelles’s spouse-abuse study, the families with the most violence were those with the highest incomes.”—p. 7."
