It's not being negative to point out the fatal flaws in that business model. I'd rather go out and make $2000 in four hours shooting Santa portraits, walk away and be completely finished with it than "make" $3500 to shoot a nine hour wedding (which, believe me, is the high end of average wedding $$$), with 20 hours of post-production and $900 cost of sales.
I did weddings for at least 15 years, and they are THE highest stress, lowest margin jobs a photographer can have. I'm glad I don't have to fool with them any more, unless you are one of my good friends and are flying me down to Mexico for a week in February. Then we can talk.
