being a chareid ledvar hashem shouldn’t absolve one from hakaras hatov. Ponevezh is alive and well today because of the incredible resurgence of frum life in Israel after the tragedy of the holocaust. Kollel students get stipends, and are allowed to learn Torah in relative peace. There are no pogroms and kosher food is easy to acquire.
Despite all the complaining, chareidi life in Israel is pretty good compared to life in Europe. Yes, the gedolim in the alte heim are far above today’s rabbis, but we have it pretty good! Be grateful.
