Anyone get the feeling that Villagers are ungrateful pricks too much of a burden to look after? Whenever a village comes under siege and there's no iron golem to protect them, it is the good Samaritan's deed to come to their aid and save their sorry butts. It's all fine and well to be the selfless hero and do the right thing, but they're still not going to have any more respect for you. In fact, the only thing that will gain you any respect from them is to trade everything you have for what little they don't, and even then that only gives you so little respect, according to the game's Popularity Chart.
I suppose you could consider their overpriced trade rewarding if you conned the librarian into buying his own books, or sold the farmer all of the village's crops, but if you're trying to be nice to these people, you're not doing it right; even if you didn't want to, you'd be better off just taking those resources for yourself. Therefore, I'd like to suggest a few things for villagers that will offer a better risk for reward balance. This topic's open to suggestions if you have any.
1.) Less expensive trades.
This benefit is the most obvious suggestion because it has probably been suggested before, and may even be in the works right now. Dependent on how popular you are with the villagers, they'll start to offer you better deals on useful items by charging less emeralds, or buy items you are selling for more emeralds. This will give players more incentive to protect the villagers, for they now provide a more valuable economic resource. The change in price is of course determined by how popular you are with the village, so better deals are harder to achieve.
2.) Cured Villagers showing their gratitude.
As you probably know, Villagers can be infected by zombies, and will become hostile. Although it is possible to kill them and get a handful of rotten flesh out of them, Mojang also added this really cool, but somewhat expensive remedy of curing them. If you throw a splash potion of weakness at a zombie villager's face, and then proceed to cram a golden apple down his gob, he'll revert back to his old non-rotting self in a matter of minutes if you keep him from gnawing your face off long enough. The villager should then be grateful his mouth isn't full of maggots thanks to your intervention, and reward you with a free item (or set of items). If the villager was previously part of a village, that will boost your popularity up by +2, because killing him would have been alot more cheaper than spending a potion, a golden apple, and 3-5 minutes of your time.
3.) Popularity boost based on siege results.
Since zombies are prone to launch full scale invasions on villagers, a player going out of their way to save them would certainly merit praise of some sort, and would increase your popularity some. The amount of popularity you gain with the village would be dependent on how many villagers were saved (or lost), how many zombies the player has killed, and whether or not an iron golem was present to help out (especially if it was a player's iron golem). The less casualties, the better the chances of having increased popularity. An additional bonus would be villagers expressing their thanks by giving you free supplies after expending a great deal of resources on protecting their village. The farmers and butchers could lend food, the blacksmith could give you a new tool, and the priest could enchant said tool. This would only happen after once per successful defense against a siege.
4.) The villager's iron golem offers you a rose.
It's not exactly much of a benefit to the player, but it's a nice gesture to show that you are on good terms with the village. It's the village's way of showing that they recognize you as a friend, and they will treat you as one of their own. This is meant to be more symbolic than it is beneficial, so it's the kind of thing you should expect when you have maxed out popularity with the village, or have achieved a firm relationship with the locals.
5.) The villagers band together to create a large colored pixel art statue of you at the center of the village in your honor.
That'd be nice.
Most of them, awesome the last one.. No. We don't need infinite wool, what happens if... two players help it? The player changes skin?

It is a good idea but let down by a 'childish' and bugfilled '5'.
Agreed. I would just plain remove any unneeded info from the first part of the OP and keep it concise. And the pixel art statue is just... meh. I don't see a need. I wouldn't hate them randomly dropping an item for me though if they like me. But just one a day, and usually it is just a trashy item like Coal or Bread, and very rarely will you get an Emerald or something, and only if they like you a hell of a lot.
