Everyone like to make money whether it's online or offline. Unless, it's a very lazy person that doesn't work hard to make money.
Sorry, that's not actually true. I don't go out to actively make money - yes, I have a job because I need to pay bills, but I don't *like* making money. If I could do what I do with building software and giving it away, I absolutely would because I enjoy doing it. (I say this as someone who contributed tens of thousands of lines of code to one of the open source forum platforms, including core code but also somewhere around 100 plugins over several years)
As for gaming, I think Star Trek summed it up best - in the Original Series, episode Shore Leave there is this slice of conversation:#
CARETAKER: This entire planet was constructed for our race of people to come and play.
SULU: Play? As advanced as you obviously are, and you still play?
KIRK: Yes, play, Mister Sulu. The more complex the mind, the greater the need for the simplicity of play.
People need to have downtime and that downtime absolutely needs to reflect culture, creativity and so on - pursuit of wealth to me has always seemed utterly hollow a pursuit when striving for self improvement, cultural development and growth are all so much more interesting.
