"People always pay a large amount of money to go to a wedding anyway..."
People paid for bus/taxi to get to/from mine in the centre of a city not far from where everyone lives, and paid for their drinks, except for people buying specific clothes for the wedding or the gifts, I don't think the people who came to my wedding spent a large amount of money just to go.
I went to a wedding the other week, wore clothes I already had and drove about the 10 minutes to get there, and had a few drinks, and brought a present, didn't cost a large amount. If you want to try rope people into a spa wedding at a swanky country club half way across the country or in Greece, yes, it may cost people large amounts, but that's down to you who organised and chose that.
Agree with the notion, that they wanted something grander than they could afford so have tried to dress it up to something more palatable.
