Answer:
d. to gain greater financial security
Step-by-step explanation:
It is not likely that a possible gang member chooses to join a gang out of a desire to enjoy more financial security. This is because any prospective gang member is likely to know that only those at the very top of the gang can gain some form of financial security, and at a great cost.
For most gang members, earnings are occasional, irregular, and can be lost at any moment. This is why many gang members have a tendency to spend fast what they earn, and are not prone to saving.
