Sour Grapes Tropes are tropes that exist to convince the viewer that not only is it unlikely that their dreams and fantasies will come true, but it's a good thing that they ''don't''. This is done by showing how a character is made miserable when getting their wishes fulfilled.
Stories that don't do this are WishFulfillment fantasies. NotThatTheresAnythingWrongWithThat. Fiction has been providing wish fulfillment for centuries. Contemporary fiction, though, often comes off as somehow ''obliged'' to show the downside of a desire. Not doing so might be seen as "juvenile." Which for some reason is a bad thing. Probably ''is'' a bad thing, if unintended.
These tropes can be used to make a FamilyUnfriendlyAesop if one of the things the Sour Grapes trope is grousing about is something the viewer can genuinely attain. It can encourage them to stay in their bad situation rather than [[DareToBeBadass doing something about it]]. A lot of these tropes have the BrokenAesop of "so don't try to better yourself."
