“More money begets more spending” seems to be an underlying result of success many people accept. In other words, the more money you make, the more you spend. Quite often, it’s the expectation of the money you should spend.
In most regards, we judge people based on our expectations of them. Generally speaking, people of certain social status or professions are elevated to higher standards.

“Hey, wait a minute, what kind of quack is going to operate on me!?!?”
