El Chapo was born into a poor peasant family and he was leader of the Sinaloa Cartel.

Pablo Escobar was also born into a poor family, his father was a peasant farmer and his mother a school teacher (pathetic shit pay in Colombia for school teachers back then.)

A lot of Mexican cartel members and Colombia cartel members are from poor backgrounds.

In my observations, bikers seem to come from lower middle class families (people that don't have trades and just work shit jobs)
