You know, when you strip it down to the bare bones, across countries and cultures, we're the same in that we believe/buy into something or we don't.
When my daughter was getting married, she told me the average cost of an average wedding in Pittsburgh (hall, catering, musicians, photographer, florist, invitations, gown) was $30+thousand. (They married in Columbia, Maryland, however.)
As not particularly affluent people, would we normally spend that on a party? Nope. As a significant moment in our daughter's life, with a huge body of folklore/myth attached? and perhaps a professional image to maintain? Plus available credit? Yep. (I have no idea what X spent. It was a great party and I think she's got happy memories about it. I'd better check ;-) )
And, at the end of the day, we have no gold to sell!!! but we participated in the stimulation of the economy, so it's all good, right?
The Circle of Life - it feels good to be part of it!
