To have 'deep pockets' is to have a lot of money
at your disposal.
The origin of the expression presumably comes from the tendency of people who have pockets
to store their local currency

clear however, is that anyone in possession of such lucky pants
is unlikely to act in a duplicitous manner, for fear of losing them to the retributive flames of truth
. This may in turn explain the origin of the term 'trust fund
