Do cage free eggs have a much larger proft margin?

Sometimes cage free eggs are double the price of noncage free eggs in my supermarket. Another example is organic milk can be much more expensive than regular milk. We see it with vegetables also.

It had me wondering, are the producers of these products making much more profit per item? Are they charging much higher prices, because their market will pay it? Or, do they have to charge the higher prices just to be on par with what the mass produced stuff profit margins are per item.
