I'm not so sure about that. I'll use a personal experience, since it's weighing heavily on my mind.
In October I joined a company and had great expectations about it. I put my heart & soul into being the best that I could be. I wanted to do something good. The company turned out to be fraudulent and deceptive, at least the person I worked for, although I did my best to be honest and sincere. I tried to change the way they presented the product and complained at meetings, seminars and directly to the manager who was the worst liar of all. I finally quit after less than 3 months and lost a good friend in the process, because she stayed. She said she needed the paycheck badly. So do I (desperately) but I said that was no excuse. Nazis said they were just doing their jobs too. Now I just read (online) that they are under investigation by the State of Florida and have been temporarily halted from selling that product. A couple of the sources are the Tampa Tribune & The St. Petersburg Times, so I guess I can rely on what I'm reading. So when the manager shut me up and told me I just didn't understand the program, and all the others laughed and ridiculed me for weeks, I was right all along. The point is, people are going to be lying cheating a**holes no matter what I do or think.

I agreed with the first sentence with the words "our world" but not "the world." We can change our personal world one step at a time, but the rest of the world is out of our control.
