As joblessness falls, skilled workers might be hard to find

Are America's employers at risk of running out of skilled people to hire?

The U.S. economy has become a seemingly perpetual job-generating machine, having steadily added workers for nearly eight years. Even with the unemployment rate now at 3.7 percent — its lowest point since 1969 — hiring hasn't stalled. So far this year, job growth has averaged a robust 208,000 a month, up from a pace of 182,000 for all of 2017.

The trend has defied the predictions of most economists. Many have long warned that as hiring surged and unemployment fell, the pool of potential hires would shrink and trigger a bidding wire that would ignite wage gains.

It hasn't happened. Many people are still being hired each month. And pay raises, though rising, remain modest.
