actually you are right, these loansharks aren't idiots. The real
mastermind nobody knows, he/she could be an accountant, business
person or even civil servant like maybe a teacher but somebody with
a high disposable income, and they have a few teams running all
over the island, each of these team dunno the existence of other
teams like terrorist cells, and nothing can be linked back to the
big boss.
They are run high tech operations with electronic databases shared
among all the teams, if you borrow from 1 loanshark team and dun
pay and try to borrow from another who happen to have your record
in their database they will know and you're finished.
Also these days they are more careful, too many people borrow money
dun want to pay and report police, I heard that now won't lend more
than $500 to any new customers. As to not borrow money, is very
hard to stamp them out, not all borrowers get a loan becuz of
gambling debts, some people borrow becuz they need a loan to tide
over their business which a bank may not lend if they deem the
business to be a startup or credit risk, some becuz of emergency
medical problems. So is very hard.
The government I feel can come up with a kind of poor people's fund
that can extend small loans like a few hundred dollars 2k at very
low interest or zero interest like what they do in bangladesh.
