Here are the daily numbers on changes in the U.S. labor force of late:

There is an old saying that demography is destiny. Baby boomers are retiring at a much faster rate than young Americans are entering the workforce.

Some obvious policies would help raise the number of working-age Americans in jobs, including cutting the payroll tax (or moving toward personal social security accounts), work-for-welfare requirements, and a greater emphasis on skills-based higher education.

The good news is that robots have already started filling millions of menial jobs. (Driverless Uber and Lyft car are already populating the roads in California.)

But to achieve 3% to 4% growth we also need more visas for young LEGAL immigrants.

Also, instead of raids on factories and farms, ICE should be raiding welfare offices.
