sure you can.
I'm happy with what I have. But if I where told I there was something that could improve it then is there a logical reason not to?

So if your boss offered you a pay raise with no catch whatsoever you would turn them down for no reason other than your already satisfied?

Okay then, you're just looking for loop holes but that has nothing to do with the your argument. You're saying if you are satisfied, I propose if you are satisfied but where offered a chance to move up why would you not. Your response is "What if I wasn't?"

lets ****** you get a pay raise because minimum wage just went up and despite your small salary you where satisfied

"cant you be happy with what youve got?"

Besides, it should make you happy to give to charity.
