Binnu was an ignorant peasant, only good at violent acts, just like Riina and the other corleonesi. He sold himself to the police too. Those people are not criminal masterminds a la Gustavo Frings, are just analphabet goat shepherds with a knack for vioolence.
Mandamenti might be less powerful such as in commanding entrepreneurs Who to hire and so on (mainly because sicily is depleted of Economic activity) but they still control a big part of sicilian politics, huge part of sicily national health system, lots of first sector (natural environment plus huge eu subsidies so a lot of scams and so on), tourist and nightlife activities, drug and prostitution (often in collaboration with black axe from nigeria)…calabria is even shittier and more crippled…should i go on?
