It's not greed, it's hunan instinct. If there's one thing 2014 has taught me, it's that to survive in this world, you need to do what you can, including making the most of a bad situation. If that means benefitting from someone else's downfall, so be it. In a way, it's survival of the fittest, manipulating the system to your advantage. I stand by my comment - those who are saying they would never do it are just butthurt they missed out.
I don't see how buying 59 mobile phones for 1p plays into this human instinct for survival.
