You say greed but I would wager that most people in the thread are not financially independent. If someone can't retire from needing money in perpetuity, is it really greed to want to move that needle from "no" closer to "yes"?

Or even just the next meal. We don't know their situation, and I've heard quite a few stories of the tech-adept being on the streets or behind bars. Some amount of greed is normal. It's when goes way beyond that, into averice that it's a problem.
