No one wants to be a garbage collector or slaughter house worker, the people who do such jobs do so because they have few/no other options. Sure these jobs are important, but do you or any of your friends wish to do either of these jobs? Probably not.

Gangsters become gangsters because they too have few options in life, due to upbringing or lack of education. Since they don't have the education or training to be productive members of society, they make their living doing scams, running drugs and prostitutes, or loan-sharking. The only people who respect gangsters are other gangsters, because they are too narrow to appreciate anything outside their own very limited world.
