Some speakeasy during prohibition paid bribes to police to keep from being raided. This may imply that the speakeasy made enough money to pay for supply and the bribes. For that to accrue they would have to have good quality liquor with a high return rate of customers. But, with all illegal operations there is always a risk of quality control and supply not being able to keep up with demand. The in income levels would be different in that the speakeasy paying bribes would probably be of a higher class able to pay a high rate for the liquor. Paying a higher rate would secure supply and pay for bribes. The speakeasy that got raided all the time had to pay to set up shop elsewhere which would eat into profit and cut out bribe money.
