Lets first focus on the things we can actually cut.
Number one in my view is weddings.
As AZ likes to point out, nobody is even getting married and we are spending so much on weddings.
But really, it is absurd that you need to spend a full year’s work on a single night.
I propose we simply stop. No half measures. No limiting to 4 piece band.
Meal in your house, and dancing in the shul. That’s it.
