It's very superior to have little money (3)

I believe the answer is:

sou

I'm a little stuck... Click here to teach me more about this clue!

'little money' is the definition.
'sou' can be an answer for 'money' (I've seen this before). I am not sure about the 'little' bit.

'it's very superior' is the wordplay.
'it's very' becomes 'so' (both can mean 'extremely').
'superior' becomes 'U' (U can mean upper-class, as in U and non-U speech).
'so'+'u'='SOU'

'to have' acts as a link.

Can you help me to learn more?

(Other definitions for sou that I've seen before include "almost worthless" , "Tiny amount of money" , "French bread once" , "Former small French coin" , "Something of little worth" .)
