Several of his comments boil down to a fanatic root belief in proceduralism. Who cares if the food sucks as long as the checkbox "waitress smiled" is checked. Also applies to a bunch of other examples, like you can be a jerk and thats OK as long as you go to church on Sunday, obsession with money, annoying advertising, consumerism/all you need for happiness is the latest iDevice, etc. The core belief being that success just means having the right checkboxes checked. That observation would shorten his list considerably.
A couple of his other comments dance around Americans being the most ignorant western culture out there (what you say Ireland has airports, and you're not all potatoe farmers?) Several of his other comments fit into this category. We really do encourage stupidity as a culture to keep the consumerism and gullibility toward advertising going. Whole classes of people who basically only exist to be milked as cash cows. Just kinda how we are, I guess.
So for those who can't get thru, these three above themes summarize his observations reasonably fairly, or at least I hope fairly.
A car in the city, is mostly just a pain.
