Lip service mostly. Nazi policies generally moved to the right since the break with Strasserism and the purge of the SA, and the "Proper"/"German"/"Volkish" social hierarchy espoused by propaganda was (for all its utopian or faux-medieval motifs) in practice directed at recreating the class structure of Bismarck's Prussia, which was viewed through rose-tinted glasses by many at the time.

True, when the conservative aristocrats showed some resistance, they were chastised (and the July plot brought an anti-aristocratic pseudo-populist turn), but when they went along with the new regime, the Nazis helped secure their position. The non-Jewish industrial and financial elites got a pretty sweet deal at first, and enjoyed it before being dragged into a suicidal war.

Right, but one could use many of the same argument against post WW2 social democrats no? The quality of life of the German working class much improved in the 1930s.

Again I wasn't arguing they did that much on their stated beliefs but I said they where an example of racialists arguing against class divisions.

To give another example from Fascists rather than Natonal Socialists (I think there is a notable difference) listen to this speech by Sir Oswald Mosley.
