Vietnamese wedding

I went to my cousin's wedding today, it was a happy day for the couple but at the same time exhausting for everybody including themselves, parents and guests.
Vietnamese weddings are complicated and they get bigger and bigger over the years. Mom said her wedding was simple, they only served tea and sweets, and there was another small celebration with food for family members. I remember seeing pictures of her wedding, she dressed in a traditional ao dai, there were two rolls of tables in a court yard... It looked like a happy stress-free day.
That was 23 years ago. Nowadays, weddings are big and wasteful. Weddings are for parents instead of the groom and the bride, because the majority of guests are parents' friends. Everybody gets to eat, to seat in a big hall, there's a professional speaker and walking down the aisle and popping the champagne bottle. The number of guests can easily be 600 or more.
Let's do some math on my cousin's wedding: they actually have 2 weddings. Today was the first one with only the bride's side, which means the bride's parents' friends and family. There were 80 tables, 6 each, that made 480 people. Not all 80 tables were full, there were about 10 empty ones which means the food for those tables will not be eaten. The groom's side will have more people, which means another 80 tables? that makes 160 tables and 960 guests. Holy crap!
The happy couple had to stand by the door greeting guests coming in. Then they walked down the aisle together (technically entered the room and walked to the stage together). Then the bride's father made a speech, sometimes all parents get to talk. Then they gave each other rings, then poured champagne, then cut the cake (that no one gets to drink or eat). After all that, the couple had to go to each table to thank people for coming, to be congratulated and toasted. When they're done making a round, they had to stand by the door as people were leaving.
As for the food, it's always the same for every weddings: green beans sticky rice, some soup, chicken, stir-fried vegetable, beer, soda, squid cake, shrimp, etc. The food wasn't any good, and there were a lot of left over, and once you're done eating off you go.
After the wedding, the bride goes home, exhausted that she can hardly take her dress off. The groom is being dragged somewhere else with his friends, always come back completely wasted. The wedding night is out of the question. Then 2 days later, it all happens again: another wedding for the same couple, this time it's even bigger, double the size of the first one. More money, more wasted food, and i'm sure the happy couple will never want to go through all that again.

I went home and told mom "if I ever get married, you're not inviting your friends to my wedding, if i can't have a small tiny wedding then I won't have one at all." Mom just laughed at me, she said it's a unavoidable tradition. I believe it will change eventually.
