Stupidity and greediness exist. That doesn't mean that how you describe an exchange isn't true. All exchanges that are made (without intervention by a third party) are almost by definition, consensual. And the one thing about the free market is, it's the only game in town where everyone wins. Both the buyer and seller are happy and unlike other (interventionist) exchanges, both usually thank each other.
When a person, after an exchange finds that they have not gotten what they thought they were getting - they either - blame the buyer as greedy or think themselves as stupid and in many cases both conditions existed.
Greed is not operating in one's self interest. Neither is not becoming educated (being stupid wrt) in the product or service you're buying. That is to what I was referring. I guess I could have been clearer.

I think we are pretty close to being in agreement Kent and my post wasn't necessarily a rebuttal to your earlier post. My frustration lies in the commentary a see made routinely about a supplier that sells a product for a higher price describing them as "greedy" or a "rip-off". I don't think either term automatically applies. Certainly if they are providing the same product with no better level of service than most other suppliers, then the market will eventually work itself out............
