This is a great point! Whenever I go to a wedding, my non Jewish Coworkers are amazed at the amount of people that are invited. To them a “big” wedding is 150+ people. My boss got married in her small NYC apartment. She was somehow able to squeeze in 50 guests. We don’t need to invite the whole town. If you can afford to do a lavish wedding, great! Do that. But we shouldn’t be as materialistic.
The best memories from weddings are the joy expressed at the wedding more so than what food was served. Frankly if you are getting more out of the food than feeling joy towards the couple, you probably should not have been invited to the wedding.
