America was worse because most of the Rabbanim refused to go there even thought New York City was the largest jewish community in the world in 1900 , over double any other place.
Things would have been different if Beis Yaakov’s and other Yeshivas would have really been pushed in the teens and 1920’s. At that time the largest “Yeshiva” was JTS and it almost failed and tried to merge with REITS because it was barely surviving
Yeah I know Yeshiva of Brooklyn and Torah Vodass are also pre-world war II, but much more was needed and even earlier places would have helped alot. Torah Vodass would have been even greater had it formed about 25 years earlier
