I honestly don't think there is anything wrong with art- whether it be music, literature, paintings, movies etc - occasionally casting aspersions at people who live normal lives, based on that very "normalcy". I happen to think I lead such a life and done mind being the subject of criticism for it. Perhaps the US is different then UK in the sense that many of us in the US have this ideal/image of ourselves being free and independent (the cowboy) when in fact in may ways we arent (the Marlboro man addicted to cigarettes), and so it doesn't seem to be that out of place for someone to remind us of that dichotomy. I recall a scene one of the oscar winning and critically acclaimed movie "The Apartment" showing the identically dark suited Manhattan ad-men commuters literally as sheep - no one seemed then(or seems now) to feel it was offensive, in fact it was considered great humor. It is part of making fair comment on social values you disagree with - there is always "collateral damage" to those who (or whose values)are the subject of the comment. I would hate to think we have gotten so sensitivity sensitive that we can't poke fun at or criticize lawyers no matter how cool they are.
I think the song is fine, but a bit dated in its imagery and perhaps a bit too narrow in its focus for my current tastes. The US is a more varied diverse place than it was in the late 50s. There is still room for criticism of issues like conformity, and those who conform, but the images would need to be more current.
