Lots here getting something done about upper-class (7)
I believe the answer is:
auction
'lots here' is the definition.
(items at auctions are divided into lots)
'something done about upper-class' is the wordplay.
'something done' becomes 'action' (I've seen this before).
'about' means one lot of letters goes inside another.
'upper-class' becomes 'u' (similar in meaning).
'action' going around 'u' is 'AUCTION'.
'getting' is the link.
(Other definitions for auction that I've seen before include "Public sale to the highest bidder" , "event with lots involved" , "Offer to bidders" , "Public sale by bid" , "Public bidding sale" .)
