One of the main points of the article is that the number of payroll jobs are not the same thing as the number of employed Americans.  Jobs have been trending toward part-time as this allows employers to avoid benefit costs.  In order to make ends meet, many Americans work two or more part-time jobs.  Therefore, the announcement on Friday of 148,000 new jobs does not mean 148,000 more employed Americans.

There is another problem with the payroll jobs.  Although the figure is nonfarm and does not include imported agricultural labor, it does include immigrants on work visas, such as H-1B and L-1 visas.  This means that job gains in information technology and software engineering, for example, might be job gains for immigrants on work visas and not for American citizens.  

As the payroll jobs number reflects reported information on payroll taxes and unemployment insurance, citizens and immigrants are lumped together.  The percentage of new jobs taken by immigrants on work visas is not broken out.
