Paradox?
All this proves is that the superior being knows we a basically materialistic species fsacinated by all forms of material gain. No matter what happens he knows we are going to take something. In the end, he knows that he is superior because we fell for the scam, $1000 or $1,000,000 and will either 1) know enough to avoid this planet in the future or 2) know he has a couple billion fish to fry when he sets us up for a bigger scam.
Besides, I want to go behind the green curtain and see who this "superior alien" really is. Sounds like Oz to me.
