A Lonely Rich Kid
may very well be brought up in a Gilded Cage
, but to show the kid actually being lonely, a sad kid isn't enough. To actually show loneliness you'd probably need to juxtapose it against kids who aren't
lonely. There are a lot of things you can infer from that image, but loneliness isn't all that high on a trope called Gilded Cage
. The image shows primarily that she wants out, and maybe secondarily that she wants out to meet friends, though that's still left to your imagination. That, however, still requires her to be held inside against her will.
An image that's just a Visual Pun
does not illustrate the trope and at best doesn't actively harm the page, which means it's marginally better, if that, than no image at all. This one is also kind of close to its actual trope definition, which means there's a high chance of misinterpreting the trope to just mean a decorated jail.
