As the railway plan was initiated, Franz did not forget the other two core industries, though the government's direct involvement in these industries was much less.
In a way, the manufacturing industry can be seen as a whole. The food processing industry could be separately peeled off, with no other factor but the simple ability to make money.
At present, the main source of foreign exchange for the Austrian Empire is agricultural exports, which include refined agricultural products and exports of raw ecological agricultural products.
Undoubtedly, the profits from exporting processed grain are much higher, which can drive large numbers of employment and bring substantial tax revenue to the country.
From the perspective of economic development, this is a point of GDP growth. Franz even hoped that the profits from agricultural exports would offset the trade deficit.
