Warning: I'm going to rant here. Definitely my longest DDF post ever. If you don't read it, I don't blame you. If you quote my post, take out all the text so that it doesn't take up a whole page.
I just looked at the numbers in the Mishoacha article, and my one question is: Are the 7 case studies in their article an accurate representation of what people across jewish communities spend on weddings?
If they are an accurate representation, then I think we have a big issue aside from the actual wedding costs in our community. I'm not saying that a 250-person-wedding campaign isn't a good idea, but I think there's a completely separate issue here that needs to be addressed as well.
Looking at 4/7 of these cases:
1. Somone "lives from paycheck to paycheck" and "doesn't have money for extras" but spent $14k on gifts for the kallah and $17k on furniture/housewares/linnen/apartment setup? In addition to this campaign to reduce your $24k share of the actual wedding expenses, maybe we can work on cutting down the $31k of gifts and home furnishings?
2. Someone is "solidly middle class" and "carries credit card debt from month to month", but spent $7k on sheitels, $5.5k on clothing, $7.6k on shabbos sheva brachos and $2.5k on a watch? Reducing these other expenses might yield more savings than a klal-yisroel-wide revolution to trim your $27k share of wedding expenses a bit.
3. You say that "while the business is doing well, we still have some debt to pay off" and you "we didn’t have any money in savings when our daughter got engaged" but you spent $16k on a vort, $8.5k on sheitels, $9k on clothing for the kallah (plus $5k on the gown), $15k on shabbos sheva brachos, $17k on gifts for the chassan (including a $2,350 silver kos), $11k on furniture, $6.5k on linens and towels (!), and $10k on piece of jewlery for the mother? Compared to trimming some of those ~$100k of expenses, I'm not sure that trying to cut down some of your $32k share of the wedding expenses is really such a big deal.
4. You're someone whose finances mean that "it takes a while to save up money for a wedding" but saved up to spend $7k for a chosson watch? $17k between flowers, tablecloths and flooring?
For someone that has lots of money and want to spend it on a comfortable lifestyle, $12k of furniture, $9k of clothing, a $7k watch, $17k of gifts and a $15k shabbos sheva brachos are all nice luxuries to have; but for anyone who's trying to work on cutting down the costs of marrying off their children, those are not necessities, they're luxuries.
People who carry credit card debt can buy cheap furniture. People who have no savings can buy a linens and towels for $1,000 instead of $6,500. People who live paycheck to paycheck can furnish their young couple's apartment for less than $17k. These items are simply not what people in these economic class can afford.
Please tell me that these cases are not an accurate representation of what most people spend.
/end rant
TLDR: If the cases presented by Mishpacha are an accurate representation of what Klal Yisroel spends, then on top of a 250-person wedding campaign I think we have to work on understanding necessities and luxuries.
