As you can see, working-class members of every group are less likely to have received a vaccine and more likely to be skeptical. “No matter which of these groups we looked at, we see an education divide,” Mollyann Brodie, who oversees the Kaiser surveys, told me. In some cases, different racial groups with the same education levels — like Black and white college graduates — look remarkably similar... There are still differences by ethnicity, because racial inequities are a reality of U.S. life. Many Hispanic Americans, across social classes, say either that they want a shot but have not yet received one or that they are waiting to see how the vaccines affect other people. And there are even bigger differences by partisanship, with many Republicans, including professionals, skeptical of the vaccines. But you can’t understand the country’s struggle to vaccinate everyone — and save thousands of lives — without understanding the class gap.
