Public opinion is highly lopsided when it comes to weighing the work effort of immigrants versus whites some 64% of adults in this country agree that immigrants work harder than whites at low-paying jobs, compared with just 26% who disagree. However, an even higher percentage of blacks 75% say that whites are out-worked by immigrants at low-wage jobs; just 61% of whites say the same thing. One pattern is consistent regardless of race: Both whites and blacks are more likely to say that whites are outworked at low-wage jobs by immigrants than to say that blacks are outworked at such jobs by immigrants. Public opinion on these questions hasn't changed much since 1986, despite the fact that this country has experienced a heavy influx of immigrants, many of whom have come to work at low-wage jobs, in the past two decades.
