NYC Yeshivas Rise in an ולאם מלאם יאמץ Trend

Rashi on  ולאם מלאם יאמץ says:

לא ישוו בגדולה כשזה קם זה נופל וכה"א אמלאה החרבה (יחזקאל כו) לא נתמלאה צור אלא מחורבנה של ירושלים 

[Yaakov and Eisav] will not be equal in greatness. When one rises, the other falls. And it similarly says (Ezekiel 26) "I shall be filled with her that is laid waste" [, which is expounded to mean that the alias for Edom called] Tzor is only filled up from the ruins of Jerusalem

NY1 (h/t YWN):

It's been a difficult decade for the city's Catholic schools - a steady and significant decline in enrollment means there are now 47,000 fewer students and a hundred schools where the doors are closed for good.

It's the exact opposite of what's been happening with the city's Jewish schools, where a growing Orthodox population has fueled a boom in Jewish education.

Now these opposing trends have crossed, and for the first time, the city's Jewish schools serve the most students outside of the public system.

"That trend of growth is certainly going to continue, particularly in the yeshiva and more Hasidic circles, where the growth is really exponential," said Yeshiva University Vice Provost Scott Goldberg.

Looking at state data, the city's Independent Budget Office found that 10 years ago, there were 134,948 Catholic school students compared to 73,254 Jewish school students. Now the number in Catholic schools has dropped to 87,301, significantly fewer than the 94,589 in Jewish schools.

NY1 also analyzed the state's numbers and found the enrollment differences will likely increase rapidly over the next few years.

As of now, the state says Jewish schools have about eight percent more students than Catholic schools. But when you compare enrollment for the first and second grades, Jewish schools have 53 percent more students.

...

In fact, Goldberg says the State Education Department is likely undercounting the population. Census reports conducted by a Jewish foundation have found thousands of additional students attend city yeshivas beyond those in state records.

That census comes out every five years, and the latest is about to be released. Many expect it to conclude that the city's rapidly expanding Jewish schools are already serving more than 100,000 students.
