To look at it another way, today there are about four times as many people working in service jobs as in other kinds of jobs.

换一个角度看，今天在服务业中工作的人数大约是其他行业的4倍。

When lockdowns were imposed poorly paid people in service jobs dropped out of the workforce, for instance, which had the effect of raising average pay as measured by statisticians.

例如，当实行封锁时，从事服务业工作的低收入者就会退出劳动市场，根据统计学家的计算，这将会提高平均工资。
