If there are 94 million CITIZENS out of work, why do we need 11, 20, 30 million illegals here?
Incorrect. There are 94Mil who are not even in the labor force. You would have to add the additional people who are unemployed, as well as the number of people under 16, to get the actual number of citizens not working.
Also, those numbers don't include people who are working alot less than they want/need to. If you made money during the week, you are counted as having a job. 100%.
To summarize, the employed are:
All those who did any work for pay or profit during the survey reference week.
All those who did at least 15 hours of unpaid work in a business or farm operated by a family member with whom they live.
All those who were temporarily absent from their regular jobs because of illness, vacation, bad weather, labor dispute, or various personal reasons, whether or not they were paid for the time off.
