This simply is not true. Plenty of connections with socialism if you read the 25 principles of the NSDAP as translated at the Nuremberg Trials.

For instance: "All citizens must have equal rights and obligations", "Abolition of unearned (work & labor)income. Breaking of rent slavery", "Nationalization of all associated industries","Profit sharing of heavy industries","Expansion on a large scale of old age welfare","Provision of a law for free expropriation of land for the purpose of public utility". "Enabling of every capable and industrious German to obtain higher education", "State to support all outstanding intellectually gifted children".
