Lazeelink, Obama did create the jobs in the service industry. They simply replaced other jobs such as those in manufacturing as more and more corporations realized that they could get much cheaper labour in third-world countries, thus making higher profits. Also, Americans, like most Canadians prefer to pay lower prices for the things they buy, so obviously Chinese goods replaced most consumer goods and there was nothing that the American government could or can do. 
On top of all that, robots have been replacing workers in jobs requiring lower skills. 
But despite that, unemployment is very low in the US. What future governments need to do is ensure that workers get a living wage no matter where they work. If you or Trump have any better ideas, I'd love to hear them.
