Deletion of Grey-collar

Comment: The term is in persistent and wide use.  I added some other definitions and cites to the article a moment ago.  The article needs ''improvement'' not deletion. I also add that ''academic references'' may be the preference of the nominator but these are not required by . There's no deadline to add such references in any case
Stance: keep
