I can see the connection clearly, if a large % are paying no tax, the Italian government cannot pay it's share of it's EU obligations and would not have need an EU loan to avoid bankruptcy if they did pay their taxes. I don't know about the 'black economy' but certainly tax evasion / avoidance is an issue in S Europe.
Anyway the figures for Italians working 'in nero' are 19.7% in the South, 10% in the centre/north.
Highest is Calabria with 27%, lowest is Lombardia with 7.9%.
