"Of course they do. There are evil people in the world. These people need to be exposed and dealt with. But that is NOT what's being advoated by the left."

That's precisely what is being advocated. It isn't restricted to "evil people" though. A political climate that allows and even encourages lowering wages and restricting worker rights while rewarding the largest corporations leads to these unethical behaviors with little if any accountability.
Demanding that the wealthiest pay their fair share in a progressive tax system is NOT class warfare. Suppressing the workers and removing their rights to negotiate is class warfare.
Corporations should exist and their executives paid for the betterment of society rather than just for themselves.
Otherwise, those corporations must be dismantled and their executives punished.
Make no mistake, that is not a statement to suggest that corporations are bad. Additionally, no corporation should be permitted to become so large that its failure creates the upheaval that we have witnessed recently.
They should not be allowed to employ predatory practices that eliminate competition and bury local small businesses.
Legislating effective regulations with the power to enforce them is the way to stop this rape of the greatest resource of the economy--the working class.
