The real reasons for the decline of unions have virtually zero to do with the Democrats.
Nixon's 5 SCOTUS appointments in 5 1/2 years sure did starting with that 1971 PPG decision to steal health benefits from a profitable company's retirees.
So did corporate mismanagement and failure to reinvest.
And modernization for the companies (like mine) who did reinvest. There were 1800 people at my plant when I started, 500 when I retired.
The 500 put out 2X the steel that the 1800 did because of modern equipment.
And greedy companies moving to China.
And, I might add, those corporations that you criticize currently have higher standards towards women and minorities than our current federal government.
If our CEO said just one thing that Trump says daily, he'd be gone that day. HR takes that bullshit damn seriously and the unions work with HR to provide a modern harassment free environment.
Blaming Democrats for that isn't accurate.
