you are mistaking greed that is pervasive these days
in this
society
You say that like it's a bad thing. Greed is what makes free markets
work efficiently. When you're buing a product, it's in your best interest
for it to be the case that everyone else buying that product is trying
to maximize the value they receive per money spent. Similarly, when
you're a seller, it's in your best interest that all the other sellers
are trying to maximize their money received per product sold.
I do mind seeing the latest gizmo go on sale for $500
rather than $50
on ebay, but there will always be a bunch of people to try to do that.
And either there will be people willing to buy that that price, or the
price will drop, or the sellers will stop trying to sell them.
