>>>We don’t even reach the ankles of our Elter Zeidas and Bubbes in Yiddishkeit.
Perhaps you don’t but I can think of plenty of people who are Talmidey Chachomim and Yorey Shmoyim whose great-grandparents were total Am Haartzim and who were not particularly frum. While it can’t be judged who Hashem values more given the respective circumstances faced by both groups on an external level it doesn’t seem correct to say that the current generation does not have many who far surpass their great-grandparents in Yiddishkeit.
