I don't think greed and selfishness are good. Looking out for your own interests is important, but that doesn't need to be "greedy and selfish". Those words define an extreme that aren't necessary to survive or even do well. I spend a lot of time volunteering with Drupal, the software that runs this website. I've given a great deal of my time just because I enjoy helping and I love the software. It's coming back to me in the form of freelance work because now my name is out there. So I'm getting something out of it in the end but that wasn't my goal. I wasn't being greedy or selfish and yet I gained. This is just one example but there are many more. I think if you live your life in a way that you give at least as much as you take you'll find you get plenty without ever being greedy or selfish.
