German had scientific base long before world war. Remember Bayer's Asprin which american company stole from bayer after world war II. They used to manufacture their own plane,automobile, tank and other hardware. After world war II, they build on that base.
Unlike India where is still lack of primary education amongh its people. Common man in those days didn't knew whats going on. Only previleged Class, who were rich and can send their children to foriegn country could relise that britisher are looting India with India's so called kings. All important leader before 1947 were from rich educated class like Ghandhi, Nehru, Lala Lajpat Rai, Bal etc.
