My SIL’s wedding was over $30,000 and my parents in law had to get a second mortgage on their house to pay for their portion of it and my husband said my SIL had to wipe out her life savings to pay for the rest. Now, her parents are so broke her dad is in his 70s and will never be able to retire.

It is hard to see them burdened by the debt of a single day. If It were me I would have had a hard time enjoying my wedding knowing the high toll it would take on my parents, even if they willingly footed the bill.
That’s unfortunately really common today. People have bought into the wedding industry’s fairy-tale glamour and feel that their “special day” deserves to have no expense spared. It is so not worth it. I’ve always said that I didn’t care about the details of my wedding as long as at the end of the day, I was married to my best friend. I have always been more interested in the marriage itself than the hour it takes to begin it. I ended up having a wedding 1/3 the cost of hers and neither me nor my parents are burdened with debt from it. All we have is beautiful pictures and happy memories. And everyone still had a great time!
The article also brings up a lot of good points about the other ways people go into debt starting out in their marriage. I know too many people my age who get married just after they graduate and immediately buy a big house and new cars to go on top of their student loans. They want to live the lifestyle they had when they lived with mom and dad, without realizing mom and dad started off with a much, much leaner lifestyle. It took their parents many years to reach the level where their children now want to start off.
