I don’t know why you would have such an urge to be melamed chov. From the context, it seems that you’re talking about entertainment type stuff, which is just part of people keeping their minhagim over pesach, spending time with their large (ka’h) families, and doing the mitzvah of simchas yom tov, which, contrary to some people’s interpretations might involve happiness.
Besides, of what relevance is what one shul raises in light of the massive amounts of chesed that Klal Yisroel does before Yom Tov? How many people work days and weeks to provide the non-profit yom tov sales so that families with less means can get chicken, potatoes, matzah, etc at a good price? And how many of those people shop at the same sale as everyone else but aren’t allowed to pay? Have you seen what Tomchei Shabbos does before Pesach? I used to volunteer (a small amount) and before Pesach especially, their warehouses were full of insane amounts of food, which was bought with tzedaka, and packed and delivered with chesed. Klal Yisroel has no shortage of altruism, and while I understand that someone experiencing frustration might in a moment of weakness forget about that, the suggestion that we are bad because we don’t do enough with *our* money is preposterous and should not have made it from the initial thought to a post on YWN.
