I've had a look at some of the wedding photographers charging that top price and didn't see any skill that was different from those charging hundreds. But it's all down to marketing, the bride will then name drop that she has hired x photographer for her Royal Wedding.
I've seen a few new wedding photographers spring up in my area, even the guy who tried to sell me advertising space did weddings at the weekend...
"Yeah we do black and white as well. We convert it to black and white and leave the flowers in colour."
There are more cowboys and tacky photographers than professionals and people don't know any different, I'll let them get on with it.
I've seen these seminars training people up to be wedding photographers close to my area. Yes they'll earn thousands from that weekend, but I wouldn't be encouraging more people to compete with you!
