I read the article and said whoa at expensive weddings.
Even a small and subdued, tasteful wedding can run well above 5K. Hell, my friend is getting married in a month and his photographer is costing him almost as much as my entire wedding two months ago.
A lot of the cost savings is the willingness to do stuff yourself, find someone who will do stuff for cheap, and, well, doing stuff yourself or leaving it out of the wedding completely.
$27K is insane, though. If the couples would even take half of that and put it towards the down payment on a place to live or to pay down high-interest debt, the marriage would start off on a lot sounder footing than a huge wedding would.
