It's all about credit risks. TD's incomes are not fixed and vary
day to day. They are daily waged.
Many TDs are gamblers, owe credit card money, owe banks money,
owe Ah Long money, womanisers and drunkards. So TDs fit the banks
profile of somebody who is in the high defaulter risk group.
Just like insurance loading on young drivers.
And TDs are not well educated. If they are not driving
taxis, they will not be able to find another good job to pay off
that loan.
Not every TD, but generally speaking.
