While the 178,000 jobs the United States added in November were consistent with projections, the combination of a low unemployment rate and a stable-or-shrinking labor force implies that the economy won’t be able to keep that up for long. If employment gains are going to continue at that pace, it will have to be because more Americans join the work force.

The pool of people who formally count as unemployed — those who say they want a job and have looked for one in the last month — is down to 7.4 million, the lowest since November 2007. To keep up that speedy job growth, employers will need to pull in people who don’t fit that definition but who are able and willing to work.

The economy isn’t perfect; it never is. But Mr. Trump will be inheriting an economy largely healed from its trauma of the last nine years, and with most indicators pointing in the right direction. Everyone can hope that the next chapter in that economic history of the United States will be a more boring one than the last.
