smerel, I am talking about 1920-30s specifically. I’ve read a very detailed thesis on the topic some years ago and it sounded convincing. Sochnut centralized funds provided by private donors and directed them to agriculture rather than cities as original donors preferred. Manufacturing in cities was able to provide a living and an economically viable community. Agriculture was losing money, so more and more funds were required to support them.
German Jews in particular were reluctant to come during early nazi years, leaving their parnosa behind.
