Ever consider that most minority gang members don't want to control businesses, unions, or large scale rackets?
They clearly lack the sophistication amd intellect to do so. Its not that they dont want to, its that they couldnt even if they wanted to. First , you would need to let them know what a pension was, then what a union was, then explain what a union is and why they wre profitable. Lets not even go into textiles and construction.
