Our definitions of "comfortable" are very different, as is your self-perceived definition of "not rich."
I'd say this in much much harsher terms, but I think you get my gist.
"No refuge could save the hireling and slave
From the terror of flight, or the gloom of the grave"
Then, you have to take into account the proportion of tickets that were for 3D movies vs. non-3D. If every ticket sold for Transformers was in 3D, and no tickets sold for Twilight were 3D, then even though Transformers made more money, there is a much smaller disparity between the number of tickets sold for each, etc.
Best line: "Well, there were 4 supermen..."
