create jobs. can the economy generate 25 million jobs? >> highly unlikely because labor force growth demographics, how many people who are working in the labor force available to work, that is growing at 0.5% a year. there's simple business cycle math we call it. the potential gdp growth if you want it 3% or 4%, labor force growth plus productivity growth has to add up to 3% or 4%. >> got it. >> right now labor force growth is expected to be about 0.5%. that's demographics, set in stone. >> right. >> we switch to productivity growth, that has been 0.5% a year on average the last six years. if you add 0.5% plus 0.5% is 1%, a far cry from 3% or 4%. i love playing this game. you have to get productivity growth way up to 3.5% on a sustained basis. to put this in perspective, twice as fast as president ray gap had during his term.
