Why do you think the Nazi system of systematic genocide was so brutally effective?

Entire explanation down below

Explanation:

The Nazi system of genocide was incredibly effective by working from small bricks. To the great structure in the 1940's. It started with just a couple of beatdowns from the SA, discriminations behind closed doors. They were even effective at hiding their anti-semitism during the Olympics. Then it started even more, at first they did want to kick out all the Jews, even send all of them to a distant land. But no. They didn't want to risk an independent Jewish state which could fight Germany, no they couldn't risk that. Many of them worked on solutions for eliminating jews. So they decided to kill them all, sending them off to "work" Only for them to come back in ashes. There's a reason why it's called "The Final Solution." Isn't it?
