True, if you state it that way.
But really, most American liberals would say their mantra is closer to we all have to EACH OTHER. That means it isn't all about giving it away; it's also about getting back.
Every human is an individual. We all have survive as individuals. But now our world has become very complex. All of our lives are interwoven and overlap. Almost everything I do, affects you, by some degree of separation.
This world works better if we coordinate, cooperate and negotiate. Just "helping others" is condescending and ineffective.
