<p>I don't believe you can ever have "enough" That is the curse of humanity, we constantly want more, never satisfied. There is always something else out there you could get if you just had a little more money. Or you could help more people than you do now if you had more money</p>
<p>Until or unless we live in a utopian society where everyone's needs are met simply by asking (like thats ever going to happen) I think people will also have an interest in making and accumulating more money/wealth</p>
