It may be a cultural thing, I'm a brit, you're like from the US, but yes over here there is a culture of altruism to a degree that may be greater than in the US (eg. over here we donate blood for free). I'm talking monetary compensation thought. On a personal level I try to help because another's happiness becomes mine.
Pretty sure the majority of blood donations in the US are free (or freeish, like you might get a donut and orange juice).

There you go, so you help others to feel happiness yourself. In which case, its not purely altruistic.
There is no such thing as pure altruism, where did I say there was? (https://en.wikipedia.org/wiki/Altruism#Evolutionary_explanat...) I gave my own reasons, that's all. But it's not monetary.
Why do people like you seem determined that nothing good can exist in other people. Your tribe turns everything to shit.
Philosophically speaking, do most people do something out of pure altruism? I personally don't believe so. Everyone has an agenda - be it to feel better, to score brownie points, to make people like them, etc. Why should we expect for-profit corps to be altruistic? We should remember their for-profit motives and also accept they can do good deed for non-altruistic reasons.
