Organizations like the Yakuza, 'Ndrangheta, Cosa Nostra, the Irish Mafia, etc, are part of many countries, to bigger or smaller fashion.
But to someone from those countries, what do you think was the original/historical cause for such organizations to develop?
My country - Portugal - has some degree of presence of these organizations but, to my knowledge, we never developed our domestic version of a crime syndicate. And we are not a bunch of choir boys. Something just kept things from forming. And that intrigues me.
So, what is the understanding of someone from a country where the organizations exist?


In America, we have three kinds of organized crime. Executive, Legislative, and Judicial.
That is institutional corruption, not organized crime. The two can touch and even overlap to some degree but are the same.

He already said America.
In my country all governmental branches belong to one single crime organization.
