LOL. Do you just make this stuff up? The Jews were 3% of the US population in 1941. And most weren't affluent. The Jews at the time weren't much better off than the Irish. The Italian American community had much more influence. But still, indigenous native born Americans were far and away more in control and certainly more affluent. Anglo-Saxon Protestant home grown 4th generation and more where in charge. Baptists for the most part. The recent influx of immigrants were just newly arrived workers.
US policy could hardly be considered pro-Jewish. American sentiment at the time didn't even allow for Jewish refugees from Germany to immigrate under asylum protection. This kind of flies in the face of your claim doesn't it. We sent 10s of thousands back to Germany who were subsequently executed. A point of embarrassment following the war. Almost half the country leaned towards entering on the side of Germany and Italy prior to Pearl Harbor.
So no. It was just the plain old American melting pot. Germany did not by any measure have a chance in hell of doing what they set out to do once Hitler made the mistake of declaring war on the US. It only further emphasizes his lack of intelligence in regards to military matters. He was a mouse in terms of geopolitical savvy. This likely played in his favor before 1939.
