"If you say the USA economy is good, where is it good? Where are the new jobs being created? "

I live in California, and regarding California, I agree with the following quote about California firing on all cylinders:

“An unemployment rate in the 5% range is what you see in California when it’s firing on all cylinders,” said Robert Kleinhenz, an economist at Beacon Economics, a Los Angeles-based consulting firm. A rising minimum wage, as well as new labor laws mandating paid sick leave and increasing the liability for labor violations, have not prevented employers in the state from adding to their payrolls.

California employers capped off a solid year of job growth in 2016 by adding a net 3,700 jobs during the month of December, the Employment Development Department reported Friday. The unemployment rate was 5.2%, down from 5.3% in November.
