Interesting point and I agree with you. However, automation is starting to take even those traditional service jobs away. Banks without bricks. Restaurants with order/payment tablets at the table. Doctor's offices without clerks. Even the job I retired from as a financial analyst has been replaced by a series of algorithms. There simply are not enough jobs at Walmart to accommodate everybody. I have no solution to address this brave new economic world.
Bring back the skilled trades like plumbing, electrical work, mechanical repair, engine repair. That can’t be outsourced overseas.
And deporting 20 million immigrants “here to work” frees up that many jobs for natives.
