How will non-rich citizens make a living if jobs keep getting replaced by robots and are outsourced?

Decades ago a factory job could support a wife and kids until retirement and they offered insurance, benefits, etc. Now, no more unions, those jobs as well as tech and customer service jobs are outsourced, and anything left in the US is mostly being replaced by a machine or robot. Assembly lines had 50 guys in the factory, all gone due to 2 robots assembly something and only needs a few men to monitor them. Blockbuster and Borders were destroyed by online video streaming and Ebooks. Wages also aren't keeping up with the cost of living. The rich get all these tax cuts even if they outsource every job they make, but us "little people" keep getting the downside. I'm young and very scared of the future. Technology and new companies use to make jobs. Now one guy can make billions of dollars with a few friends only.
