The NYT:

To put this in perspective, the difference between a [Ford] Focus and an F-250 over five years is $60,000. The annual pretax income of a typical family in this country is also about $60,000. So choosing a F-250 over a Focus is like volunteering for a 20 percent pay cut.

Of course, the same math applied when gas was cheap and this kind of comparison was progressive rather than regressive.
