Went to Iraq and Afghanistan. In both cases, I went to training beforehand; between the training and what we see daily in the media, and the few things you can look up for yourself (such as Afghanistan has a 70% illiteracy rate), you go over there with the thought in mind that they don't know much, and we're going to help them.
I saw most of my compadres spend their entire year with that mindset. With all due bragging, it took me about two months to realize: They're no different than us, and in some ways, much smarter. For example, I worked with an Iraqi on particular things related to my career field; he knew much more than I did about the subject. That "illiteracy rate" for Afghanistan? Give them access to a computer and the internet, and illiterate or not, they know how to find pictures and videos (all kinds of pictures and videos....).
I worked with an Afghan who kept asking me to purchase equipment that was needed for a major event in less than a month; I told him that our American supply system meant it would take me up to six months to get the equipment, and he really should have been planning ahead and talking to my predecessor to get the equipment. A couple of days later, I told him we had sent out a request, and asked for a "rush"; but it was still going to be a minimum of six weeks. He calmly waved me off and told me he had purchased the equipment the day before.
THAT was when I realized they didn't really need our help. And I started asking myself, why was he asking me for the equipment if he could get it so easily? And it dawned on me: Because he didn't want to use his own money.
If I offer you a free drink, are you gonna say "no, I'd rather pay for it myself"?
And when I figured that out, and started looking around at what was going on, and what we keep perpetuating in some of the other countries around this world, a lot more things make sense.
Differences between the races? Maybe physically. Differences between cultures? Definitely; the way we're raised, the political and religious systems we're raised in, have big influences. But when it comes down to it, we're all pretty much the same: If someone offers us something free, with no strings attached, we don't usually hesitate.
