In both 2018 and 2019 nominal wages rose by more than 3%, the fastest growth since before the recession a decade ago. Americans at the bottom of the labour market are doing especially well. In the past year the wages of those without a high-school diploma have risen by nearly 10%. Intriguingly, this has come as America has turned considerably less friendly to immigrants, who are assumed by many to steal jobs from natives and lower the wages of less-educated folk. The two phenomena may be connected—but only for a while.
