Simpler to cross line after money gets more paltry (8)
I believe the answer is:
'more paltry' is the definition.
('measly' can be a synonym of 'paltry')
'simpler to cross line after money' is the wordplay.
'simpler' becomes 'easier' ('easy' can be similar in meaning to 'simple').
'to cross' means one lot of letters goes inside another.
'line' becomes 'l' (used when specifying particular lines from a poem).
'after' says to put letters next to each other.
'money' becomes 'm' (abbreviation in economics).
'easier' enclosing 'l' is 'easlier'.
'easlier' put after 'm' is 'MEASLIER'.
'gets' is the link.
