There are two tags that are the same except for capitalization:
"Rich man/Poor woman": 237 results
"Rich Man/Poor Woman": 46 results
Not only does the second tag have fewer results, it also has an incorrect description which describes the opposite of the tag name:
"The depiction of friendship, romantic, or sexual relationship between a wealthy woman and a poor man."
I suggest that the second tag be deleted and/or merged into the first tag (not sure if there is a way to do that).
Barring that, the description of the second tag should at least be corrected to say "wealthy man and a poor woman".
