'cry of exasperation' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'a nation having failed to invest capital in growth' is the wordplay.
'having failed' indicates an anagram.
'to invest' means one lot of letters goes inside another.
'capital in' says to take the initial letters.
The first letter of 'growth' is 'g'.
'a'+'nation'='anation'
'anation' anagrammed gives 'notaain'.
'notaain' placed around 'g' is 'NOT AGAIN'.
