My Miami 1980 research has led to a Miami Herald story:
"The tumultuous Mariel refugee influx of 1980 is back in the news — this time at the core of a roiling debate about whether immigrants hurt less-educated native-born workers. The heated arguments focus on the new work of a Cuban-born Harvard professor, George Borjas, who concludes that Mariel caused a drastic drop in pay among native-born Miami high school dropouts — the majority of whom were black." That story is available HERE.
A companion Herald story discusses the discusses the politics of immigration, including Borjas' idea of taxing employers who benefit from cheap immigrant labor and how some progressives cite Borjas in rethinking their stance on immigration. That story can be found HERE.
