There are two jobs figures.
One asks established companies if they are hiring or firing. It is best at finding union losses, or problems with large "dinosaur" companies.
The other does a survey of households. This finds new start ups, small business growth.
The unemployment rate is 4.7 percent. That means that anyone who wants a job, can get one. Anyone with a job, that is not paid at market rates, can get a better one.
What do employers do when they need more work done, and can't hire people? Either you hire illegals (with the security problems associated with that) you invest in capital improvements (that makes your exisiting workers more efficient) or you move what work you can offshore.
Japan doesn't care for illegal aliens, so they have many many robots. Problem: that isn't very flexible. When the market changes, you are stuck paying off your loan on machinery. That accentuates the normal business cycle into a boom-panic cycle.
The US hires many illegal aliens. I don't like that, because I see it as a security vulnerability. A lot of US companies also work with foreign companies in India and China. WalMart in particular buys lots of stuff from China. Apple for years built their computers in Singapore.
Each has difficulties. There is a lot of work that has to be done. The US GDP is very very large. So long at US productivity is high, US living standards will be high. I don't mind it when other democratic nations such as India increase their productivity. I get concerned when China, which is not democratic, increases productivity, but eventually it will be hard for the Chinese gerontology to order a war against their customers or suppliers. The more that China is integrated into the world economy, the more the "communist" theory will become irrelevant.
