One big problem. That is not a speech made by Hitler in 1927 or any time in his life time. He never made that statement, ever.

It's the quote the Goldbergist revisionists always drags out. Hitler didn't offer those words in any speech in 1927. He didn't offer them in any speech in any year. The quote is from a 1926 pamphlet by Gregor Strasser, "Thoughts on the Tasks of the Future." It can be read online.

Gregor represented an anti-capitalist wing of the party based in the north. For holding to such views, he was eventually driven from the party by the dominant Hitler faction, then Hitler ordered him murdered (which was done).

The "Nazis were leftists" crowd--whose views, btw, are essentially Holocaust denial--are making their case by offering a quote they attribute to Hitler but that actually comes from a fellow who was, in fact, murdered by Hitler for holding to those very views.

All of the socialist leaning Nazis, known as "Strasserites" were murdered during the infamous "Night of the Long Knives" in summer 1934.
