Spanish gipsies have their own "law" (unwritten shared rules) and "judges" (patriarchs). They have/had many archaic "laws", and one cornerstone used to be that a gipsy cannot work for a gadjé (non-gipsy). This internal "law" plus poverty results in criminal activity above the average for that poverty bracket because the only legal and "legal" employment is basically self-employment. Of course you can throw your hands up and say that "crime is part of their culture", and find a basis to support racism. You can also spend resources on integration and education. Today, gipsies in Spain can work like gadjés without being shamed by fellow gipsies (or to the contrary even get praised for making a career), and all without losing their cultural identity.
