Everything Zynga does is calculated torwards having you spend energy points (such as waiting until most have Ruby mastered the earlier districts, then requiring you to go back to those jobs for more consumables) and only mastering the later levels as they are gearing up for a new level / district launch. It's a free game, so I can't see where people can complain too much.
