However, we do not see anyone forcing slavery on them. In fact, they seem to despise the idea. Dobby is still a deviation, and still a result of a very bad situation. We cannot take his situation for granted. Even now that he is free, he still carries with him a certain ammount of pride in being a house elf and taking care of others. If he truly wanted the freedom you speak of, he would have changed much more, but I believe he merely wanted a different master, and recognition for what he has been through, through material compensation
why don't they leave now? Because they don't want to, because being a slave is all they've ever known, and their biggest dream is to be an even better slave...
It seems to give them pleasure to be complimented because it's all they've ever wanted!
Somehow, I fail to see the problem with anything you say there. To live your life as you have been accustomed, doing what you have always enjoyed. They aspire to be better than they are and have a goal to work hard at doing it. And what person would not want recognition for their hard work. On top of that, they never have to worry about feeding themselves or where to live; that is alerady taken care of. Sya what you will about freedom and whatnot. However, for the work of taking care of a family, an elf lives a pretty good life. Yes, they do have to endure pain if they should betray their masters, but that is a common punishment for a soceity still locked in a middle ages mentality, and not without reason. Save, the punishment, which I doubt is the common situation, a house elves lot in life sounds little different from a normal home makers
