According to the American dream, hard work and a good education can lift people from poverty to success in the "land of opportunity." The unskilled immigrants who came to the United States from southern, central, and eastern Europe in the late 19th and early 20th centuries largely realized that vision. Within a few generations, their descendants rose to the middle class and beyond. But can today's unskilled immigrant arrivals—especially Mexicans, the nation's most numerous immigrant group—expect to achieve the same for their descendants? Social scientists disagree on this question, basing their arguments primarily on how well contemporary arrivals are faring. In Italians Then, Mexicans Now, Joel Perlmann uses the latest immigration data as well as 100 years of historical census data to compare the progress of unskilled immigrants and their American-born children both then and now. The crucial difference between the immigrant experience a hundred years ago and today is that relatively well-paid jobs were plentiful for workers with little education a hundred years ago, while today's immigrants arrive in an increasingly unequal America. Perlmann finds that while this change over time is real, its impact has not been as strong as many scholars have argued. In particular, these changes have not been great enough to force today's Mexican second generation into an inner-city "underclass." Perlmann emphasizes that high school dropout rates among second-generation Mexicans are alarmingly high, and are likely to have a strong impact on the group's well-being. Yet despite their high dropout rates, Mexican Americans earn at least as much as African Americans, and they fare better on social measures such as unwed childbearing and incarceration, which often lead to economic hardship. Perlmann concludes that inter-generational progress, though likely to be slower than it was for the European immigrants a century ago, is a reality, and could be enhanced if policy interventions are taken to boost high school graduation rates for Mexican children. Rich with historical data, Italians Then, Mexicans Now persuasively argues that today's Mexican immigrants are making slow but steady socio-economic progress and may one day reach parity with earlier immigrant groups who moved up into the heart of the American middle class.
