Okay, to avoid further thread drift (sorry Nichole) I will answer the question, but I will refrain from Gates as it is a MAJOR pet peeve of mine.
First off, lets establish something, a million dollars, while a whole a lot to me (and probably you), it's not much in the grand scheme of things these days. When I left California an average 3 bedroom home was $800k and it would be nowhere near the beach (yes, it is a bit cheaper now, but not cheap). Face it $1million does not go that far anymore, it's really not that much money it only sounds like it.
Grab a calculator, subtract taxes (say 30%?), plus a lawyer (needed to keep the sharks away from it) now divide that by say 45 years (estimate of my life remaining). Still think $1million is a lot of money?
Now...
Honestly would I really take it?
It would depend on who was paying. Some rich guy like Gates, yeah I might. Would I feel bad, probably not, he can afford to blow a million like that with no skin off his back, he would not offer if he couldn't afford it. Would I take it from someone less fortunate, no, I would reach a compromise on the price. I do a lot of sliding scale and charity work. Do I make a lot, heck no, but I can sleep at night.
