These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complicated further by the real Gardner not being nearly as much of a standup guy as the film portrays.
Glurge: A man, who is presented as moral, sees happiness in making money as a stock broker, studies at it with a high potential chance of failure for no money, and is willing to sacrifice his own son's well-being in order to do so. Also, because of this, it comes across as capitalist propaganda justifying the wealth gaps between rich and poor. If you're poor, it's because you didn't work as hard as Gardner did.
