Not to nitpick, but the common definition of greed is different:

> Greed is an insatiable desire for material gain (be it food, money, land, or animate/inanimate possessions) or social value, such as status, or power.

Keyword: Insatiable. Lots of the people in the Bay Area are simply looking for a secure future for their children. Why is this unreasonable?

Edit: Thanks Podgajski, I like your definition below better.
