(This isn't a political comment, honest! But..) After reading The Art of the Deal, I get the impression this is a lesson Trump took to heart early in life. Always using other people's money to build and do things which, in turn, seems to give him more power than he might otherwise.
Also explains how his assistants end up having to put themselves at greater and greater risk. The more they help him, the more trouble they face, and the more they hope he is able to bail them out.
