That is how capitalism works (now tell me again how great our economic system is lol, or how if we criticize it that means we're stalinists). Both parties have been in power over the last several decades as unionized jobs were lost to automation or outsourcing. If you do some reading you'll find out that machinery has probably been more responsible for manufacturing job losses in the US than moving factories elsewhere. The parties take turns blaming each other for the plight of the working class, ahem "middle class" (working class is too spicy a term for most politicians to even say): you get sick of hearing it, neither party gives a two ****s about us.
I have long said: workers have no party. In the long run the union is wasting money with DRIVE and political contributions; that money would be better spent on organizing, educating members, etc etc.
You really do not understand your ignorance of political power, who controls it, and you.
Hell yes, both parties are to blame, but the demoncrats where the easiest to buy off.
I can promise you I have read more on the subject in 2 years than you will read in a lifetime.
As an average, I read 75 books a year, on varying subjects.
Automation being the cause?
That is a modern phenomena used to keep labor costs down and most of the chips and computers are made "overseas".
I have lived to see the decline.
I built one of the first cranes to go to China in 1978 when Jimmy Carter opened the flood gates to allow trade and manufacturing to China.
BTW, I stamped my personal FU China on the crane and the international inspectors missed it.
Look for the union label, or Made in USA on any clothes you buy.
The iconic Levi Strauss union labor "Made in the USA" blue jeans are now imported.
I totally agree union members should educate themselves for the new world coming.
