How can they make even more cash if the product sells out?

If you buy it, youre "happy" with it in their eyes. So why bother? They sell out anyhow, they cant make more money if theres nothing more to sell. Doesnt matter to them because were buying it anyway, it sells out, so whats the point?
Only carrot for them to actually change anything would be if we stopped buying, but clearly we wont. Even if some refuse, there going to be someone else that will. Either way, they get everything sold.
We can ***** and moan as much as we feel like, but its never gonna do any good if we keep pushing that "buy" button.
Atleast we get the villain on the back! Thats very positive in my eyes and a first.
Several of the other movies should have had that, especially The Winter Soldier.
