I think such things continue to happen because we see it happen over and over with no consequences to those at the highest levels. You see it enough, it just breaks your will to the point that you can't even get that angry anymore. It's "rage fatigue".
Good example: I work for HP. We had a CEO, one Mark Hurd:
While CEO of HP, he laid off 10% of the workforce, bought EDS and slashed EDS salaries by 20% or so, and implented wage freezes across the board. Of course, while he cut his own salary 5%, in line with all HP employees, the Board of Directors voted to increase his bonus by the same amount. In 2008, when most of this was going down, Hurd had a $23 MILLION bonus, the largest of any CEO worldwide. This was about 18 times larger than his actual salary.
He then:
1. Hired an ex-softcore porn actress as a "marketing consultant" (to be fair, she did have a business degree).
2. Got some "personal consulting" on the side, if you catch my drift. (It should be noted that Hurd is married.)
3. Used his personal expense account to pay her hush money, until she finally filed a sexual harrassment suit.
4. Resigned, and collected a $34 MILLION severance package. Let me re-iterate this:
the man lied, cheated, and embezzled corporate funds, and in return he was PAID more money than I'll ever earn in my lifetime.5. Was promptly hired by Oracle, with a signing package worth around $200 MILLION in stock options and bonuses.

So, when you see something like that...I mean, what the hell do you do? You spend your whole childhood being taught that hard work pays off, and stealing is wrong, and bad guys will be punished, and then this. Suffice it to say, I've been looking for a new job ever since, and will be quite happy if HP crumbles into the dust after I leave. I also daily hope to hear that Hurd was disemboweled by a pack of wild dogs, his belongings were swallowed up by the earth, and that his offspring are cursed for the next ten generations. Verily, my seething is of Biblical proportions.

It's shit like this that causes Bolshevik revolutions.
