An upper middle-class wedding on the coasts at any venue goes for a minimum of 30k. A really cheap wedding is just having in your back yard with a keg, but I don't think the OP is talking about that. A nice wedding with all your college buddies, looking at 100k.
Yeah, I dunno about that. I'm in the middle of planning a wedding at a nice theater [1], catered, open bar, with a band, for 150 people, and even if we run 50% over our current expected costs we'll be under $30K. New England if that matters.
An Indian wedding in Southern California can easily cost $120k+ given the number of attendees, the sizes of the venues required, the food, the white horse...
The second part here is in conflict with the first part...
