Pop culture exposes lies about inflation

Sixteen Candles was on TV today, and I noticed this line when they find Long Duk Dong sprawled on the lawn:
Howard: Aw, shit. I pay seven grand for a wedding, I'll never see it!

$7,000 in 1984 dollars is $14,300 in today's dollars using the official CPI rate of 3% over that period. Do you know anyone who's having a large, traditional wedding and reception in a wealthy suburb this year for $14,300? In fact, costofwedding.com puts the average cost in the film's location of Evanston, Illinois at $44,350.
