One major lesson learned from this film...
It doesn't pay to be naïve, and in the 'real world' (meaning outside of our comfort zone)... ignorance is not rewarded.
Every human on the planet is "more than capable" of deception, and some people use deception several times daily for personal gain... no matter who it hurts.
This is what 'capitalism' is based on - "get what you can, while you can... and f$#* everyone else".
Unfortunately, these people don't have a "I'm A Scumbag" tattoo on their forehead...
So be aware... and take nothing for granted. Knowledge is power.
