Sadly, I think the "who you are not what you can accomplish" is a pervasive sentiment throughout many societies and cultures across time. I agree. I really like to know I've earned what I've received. And it does happen more times than not, because I'm not really related to anyone who would be inclined to give me a hand up or a hand out.
However, many people live by the saying, "It's who you know, not what you know." Something I've always found aggravating. As you've said, why should anyone, including me, get a job or do well in anything unless they actually merit it.
And it always seems like I'd be owing favors, to a point where I don't know how I could possibly repay them, and I don't want to be slighting people in the process.
So, it is better, much better, to earn things on your own.
My wife is from Mexico, though, and she has a different point of view. Why would that be? A lack of opportunity, or at least a perceived lack? A feeling of unfairness? I don't know. I haven't been able to pinpoint it myself.
As always, though, another thought provoking topic. :)
