Your point about business practices today may be valid. But singling out Gates and Trump as scumbags as you did above in this thread is somewhat irresponsible, given that neither of them have even been accused of ethical transgressions comparable to what KT appears to have done based on public records of government investigations.
I'm not a big Microsoft fan, but the "theft" you accuse Gates of involved unpatented intellectual property, and even that movie points out that the windows concept was developed by Xerox-PARC, and was first "stolen" by Steve Jobs. The point the movie was trying to make, IMO, is that business is hardball, and when the computer industry was getting started, the ethical and legal boundaries weren't clearly delineated, it was a bit of a free-for-all. And Trump, as arrogant and boorish as one might find him, hasn't to my knowledge been accused of anything unethical (not that I would know); his big "scandal" involved almost going broke some 10-15 years ago.
As for KT, well, you can read about him on Wikipedia, or on the AZ boards if you want a more angry point of view. Even compared to your everyday semi-corrupt businessman, you cross a line when, say, you start to profit from the false hope of the terminally ill.
Another thing is that most tycoon types do a lot of non-profit philanthropy work. Now, maybe you think it's just a PR stunt, but they still do it. Gates has donated some 30 billion dollars. And the philanthropy thing is especially true for people in self-help or pop-medicine. A lot of people write books that go against the grain of established medicine or psychology, and in almost all cases, the authors have non-profit foundations that generally try to "do good" in ways corresponding to their health advice.
For example, Dr Phil, Deepak Chopra, Anthony Robbins, and (the late) Dr Atkins, all have charitable foundations that are basically in concert with their medical/self help books. Now, I'm not vouching for the validity of what any of them say, I actually haven't read anything by any of these guys except what's on the news or in magazines. And I don't mean to lump them together, except to point out that they really appear to believe that their take on health and well-being can help the world. But I'm not aware of any KT Natural Cures foundation for the betterment of mankind.
