Its not that they don't know how, they have no intention of creating jobs.  Creating jobs in the USA means moving jobs from high-return developing world nations to the lower return USA.  I means they can't ruthlessly make as much money.     They also have zero interest in making jobs because they want people to be poor and unemployed because the poor are overwhelmingly democrats and socialists.  People become conservative when they get self-sufficient.  Jobs are essential to the common men being independent financially, something the dems and the liberals DO NOT WANT.
