Labor unions will never have a hold on employment again, so it’s a mute point. All of the corporations and private equity are partnered together now with a shared goal to lower wages. Unions succeeded because the employees were a threat to the employer at the time unions were common. If all the employees struck it could affect the earnings and net worth of the executives and equity owners of companies. Now, it really doesn’t to much of a degree , because the people above the mid tier don’t necessarily need any additional private wealth. Employees now can be threatened with having their job outsourced, having their job eliminated, or having a plant moved to another country. Those threats from employers didn’t exist in our nations past. These corporations and private equity work together to set wages, so these people are wasting their time striking over pay.
