Well as a side note, I am a lover of the simple and content life, over the greedy, get-ahead-at-all cost life.
But, the key word in your statement is "generally." How do we know that this guy earned it? that this $400 million gift wasn't a case of corporate excess?
And the key part of your response is "How do we know?" How do we NOT know? Far be it for me to gauge his worthiness. I wouldn't know by which stick to measure it.
I don't think the "simple" life has much to do with it. Many rich people live in simplicity, saving for their future, using their wealth wisely, and leaving estates to their heirs. Those that I know are generous to a fault. There is nothing greedy about that way of life.
