No, the 25 point plan was announced by Hitler in 1920, including all of those socialist ideas.
And the night of the long knives was in 1934. For over 14 years, socialists like Strasser were an important part of the Nazi party, working side by side with Hitler.
Then Hitler consolidated power and eliminated all rivals - not only socialists like Strasser, but people with many ideologies. His primary target was not the socialists, but his most dangerous rival, Ernst Roehm, the leader of the brownshirts.
Even after that purge, the socialist programs continued, such as Volksgemeinschaft (people's community), Deutsche Arbeitsfront (the German Labor Front), and Nationalsozialistische Volkswohlfahrt (National Socialist People's Welfare).
> The NSV [National Socialist People's Welfare] was the second largest Nazi group organization by 1935, second only to the German Labour Front. It had 4.7 million members and 520,000 volunteer workers.
> The Nazi social welfare provisions included old age insurance, rent supplements, unemployment and disability benefits, old-age homes and interest-free loans for married couples, along with healthcare insurance, which was not decreed mandatory until 1941
