It's partially why I still play. I want my lower level friends to have a good time as I have and go through it without as much headaches as I have.
And I agree with Jaerik, we're already too deep in the hole to really get away with such a thing but I think it's a good idea to at least have options so that those who still enjoy and wish to play the game won't have to invest something they can't afford (time) and instead can use something they can (money) to get what they want out of the game on a balanced scale.
I doubt it would affect those who feel the opposite of this as they can continue to play as they normally would without paying any more than their monthly fee to play. If one is unable to afford either well then they should have considered if an MMO was right for them to begin with lol.
