Frictional unemployment usually is voluntary. Just a few years ago, when the economy was bubbling and industries like commercial services, finance and insurance, information technology, construction, and national infrastructure were growing rapidly, they could absorb all the "floating" manpower, and frictional unemployment was not a serious problem.
摩擦性失業往往出於自願，在前些年景氣熱絡時，工商服務業、金融保險業、電子資訊業、營造業及國建工程等新興產業大量興起，到處都有夾縫可以吸納這些游離人力，不會構成大問題。
