“when factories move abroad, many middle class jobs go with them.”
For-profit business exist to maximize wealth for their shareholders. In fact, that is their ONLY reason for existence. If not, become a non-profit.
For-profit businesses aren’t anymore obligated to provide “jobs” than you are obligated to provide job for your local plumber. If those “middle class” people are so reliant on a business, perhaps it is time they re-think their career strategy. It sounds harsh, but there is no need for typists, telephone operators, and a host of other outdated formerly-middle class “jobs”. Either machines have replaced or are replacing them, or cheap 3rd-world drones will.
Expenses need to be lowered (and revenues need to be increased) for any business to remain profitable. That is business 101. You can’t fault businesses for trying things to lower their expenses. What will you be complaining next — the designer shoes are too expensive for the “middle class” to afford?
I make a living by investing in stocks. So of course I know how corporations operate. I have been in the stock market for 53 years. I understand corporations better than anyone on this board. But I do not live in a vacuum. My life is surrounded by relatives and friends. I care for all of them. Most of them are in the “middle class”.
Since I am not so selfish as to only worry about myself, it is my duty to make every voter aware of how their jobs will be affected by the votes of politicians such as senator Cruz and senator Rubio, who must obey their rich donors. The rich donors are usually large share holders in corporations, and as you point out, their job is to maximize profits for the shareholders.
