Please answer a question about the following article about East Prussia:

Through publicly funded emergency relief programs concentrating on agricultural land-improvement projects and road construction, the "Erich Koch Plan" for East Prussia allegedly made the province free of unemployment; on August 16, 1933 Koch reported to Hitler that unemployment had been banished entirely from East Prussia, a feat that gained admiration throughout the Reich. Koch's industrialization plans led him into conflict with R. Walther Darre, who held the office of the Reich Peasant Leader (Reichsbauernfuhrer) and Minister of Agriculture. Darre, a neopaganist rural romantic, wanted to enforce his vision of an agricultural East Prussia. When his "Land" representatives challenged Koch's plans, Koch had them arrested.

What did Koch report to Hitler in 1933?
that unemployment had been banished entirely
