Clean up the trope?

It seems to me one of the big issues here is too many 'but they live in this area so it's ok' I think we should consider trimming or reorganzing the trope, so that large places in say NYC or fancy neighborhoods are left, but ones where the location makes it reasonable for space are removed or put in an averted section.

For instance, Friends is clearly an example, set in Manhattan with a large apartment. The Big Bang Theory is not, as it's a meh part of LA where rent is a fraction of NYC due to far more space. Or the drew carey show, since it's a meh house in the midwest.

in another pokemon anime explain is dawn's house its very big and looks above average income how dawm's mother be able to afford it without no job, maybe cause she's a famous pokemon corrdinator?!!!!

The CBC program "Undercurrents" actually did a story about this in 1998: http://archives.cbc.ca/arts_entertainment/media/topics/3624-16046/ (starts at 14:53). If this were TOW I would add it to a list of references, but I don't know where such a link might go in a TV Tropes article...
