On 'big'

I'm supposed to be working on assignments for work. Instead, I'm working on a basement* theory:

Could the social ill that causes people to buy guzzler SUVs (and consider cycling a personal affront) be the very same as the one that makes them eat fast/processed food and watch TV indiscriminately?

Is this desire to be 'big' (physically or only by mechanical extension) related? Is this the same urge to expand that makes people support Bush's Iraq fiasco? Or is it the TV they've been watching indiscriminately?

Do they really just want to be 'big'? Or do they just watch too much TV? Even TVs are getting bigger.

Why is everything expanding *except* polar ice caps and populations of besieged nations?

*Basement theory = An unverifiable theory employing tautological arguments, usually developed during periods of sleep deprivation (or substance use/abuse) - commonly a thinly disguised rant about some aspect of Western culture.
