> In the end it's really just greed.

Yeah, well their job is to get the best price for their product. Just as it is your job to get as much money as possible for your product, i.e. your talents and labors.

In a competitive economy with informed buyers this greed is what makes things cheap and high quality. Think about two grocery store owners in a small town. They've settled into an equilibria with each other to keep the status quo and not get greedy for a bigger share of the market by competing on price or quality. Then one day, seeing an opportunity, a new grocer moves in with fresher fruit, a wider variety of products and most importantly lower prices. All the customers go over to that grocery store and the old grocers have the choice to improve or die. From the point-of-view of the previous grocery store owners the new grocery store is "greedy", but it ends up benefiting everyone else.
