Agreed. There was a study I read that there is an inverse relationship between how much couples spend on their wedding and how long they stay married. My wife and I rented an Elks hall for $100 for our reception, had a friend's band play, found a cheap caterer who did a chicken dish for $8/plate. The hall provided a bar tender and it was a cash bar, so guests paid for their drinks. My wife did all the flowers herself, her bouquet, all the table arrangements, etc. She bought a discontinued wedding dress off a display they were getting rid of at a fraction of it's full cost and had her mothers friend alter it. Then their was a limo rental and a tux rental. We had my wife's sister in-law take pictures of the ceremony because she had a nice camera (this is film camera days), we also left a single-use disposable camera on every table and told guests to take pictures during the reception and leave the camera on the table for us at the end of the night, so we could develop all the film. You can get married on the cheap and still have a great time, but most people in the US want to impress their guests like they're some kind of royalty even if they have to go into debt to do it. We bought our first house 2 months after our wedding because we didn't go into debt to get married.
EDIT: This could be the study I remember:
Want a happy marriage? Have a big, cheap wedding
