Laments about teachers not getting money — hypocrites! (7,6)

'money hypocrites' is the definition.
'plaster saints' can be an answer for 'hypocrites' (plaster saint means a sanctimonious hypocrite). I'm not certain of the 'money' bit.

'laments about teachers not' is the wordplay.
'laments' becomes 'plaints' ('plaint' can be a synonym of 'lament').
'about' means one lot of letters goes inside another.
'teachers not' becomes 'asters' (I can't explain this - if you can you should give a lot more credence to this answer).
'plaints' going around 'asters' is 'PLASTER SAINTS'.

'getting' acts as a link.
