93% of private sector workers in the USA are NON-Union. The jobs were not shipped because of unions so take that one off your list.
What do you consider private sector jobs? Working in office or in factories? I got news for you factory jobs are indeed being shipped overseas. You better take your blinders down
The textile industry is a prime example of this.
Same can be said of steel
Same can be said of aviation
All three were union heavy before they declined
How many textile mills are there now compared to 10, 20, 30, or even 40 years ago?
How many large steel mills are there now?
How many large aircraft manufacturers are there now?
The greedy unions have collective bargained themselves out of their jobs.... That's a fact.
