It would be fun if you could finagle about why the whole issue of wealthy people creating wild parties doesn't bother you much considering your own admission of zealotry.
Or it does bother him but he is not bothered by the rabbonim not "banning" it.
As I posted already, inappropriate Purim parties are not at all restricted to the 1%.
I know of regular middle class couples who celebrated in a way that I would deem to be very inappropriate as well. And this all does technically bother me. Would you really like a 1000 word essay/rant against the new shallow culture of materialism? Meh, I don't have the energy..
So what exactly is the big deal if some rich dude throws a ridiculous party? To me personally it does absolutely nothing to impress, I basically couldn't care less.. I may shake my head and mutter something about kids these days...
Whoever wrote that OP letter though is despicable. They obviously hate rabbonim and we're just looking for an excuse to disparage them. It has nothing to do with the writers great pains about the party. I won't be jumping on that bandwagon.. this whole crises has nothing to do with the poor loser who needed to show off his success... Let them enjoy it.
