Environmentalists, and others seeking reform, can build on people's anger at government AND corporations by emphasizing how government caters to the interests of large corporations, wasting taxpayers' money in the bargain. In turn, government then subsidizes big corporations and relieves their tax burden. Greedy corporations then turn around and abuse their workers, who are already bearing the brunt of the nation's unfair tax system. With some work, the result might be a law to get corporate and other private money out of our elections. Democracy in this country would be advanced in a major way, as would environmental protection.
Corporations are unlikely to change their behavior voluntarily.
It seems safe to say that they can't. Therefore, as time passes corporate abuse of workers seems likely to continue and to get worse. But corporate behavior still will spark anger as real people are hurt. In sum, continuing abuse of workers' loyalty and trust will be hard to conceal. It seems very likely that, today, no one knows the answer to that question.
