Just curious: do you have a citation for that quote?
Yep... Joel Stein in the April 18, 2003 issue of Entertainment Weekly.
The full quote is:
"I found the most convincing part to be the working stiffs," said Valenti of the PSA, "the guys who have a modest home and kids who go to public schools. They make $75,000 to $100,000 a year. That's not much to live on. I don't have to tell you that," he said, vastly overestimating the U.S. poverty level and what I get paid for this column.
Funny part is, when they started actually showing the PSAs before movies, apparently they dropped the ones starring Ben Affleck, and only went with the "working stiffs."
