Only jobs that will be left will be either normal low paid service jobs that can't be outsourced, like restaurant staff/cleaners, and high end specialized jobs.
Middle class will mostly evaporate, what will be left of them will work in support of the high end jobs or as bosses of the lower paid ones/independents.
Except more and more shops to close down as good will be bought cheaply online, or digital. Further reducing the number of people in the workforce here in the process.
