Thats not right at all. I'm Jewish and sure my religion says I am chosen by G-d, but that doesn't mean i shove it in other people's faces.
The reason why is because the Jews possess a sort of image survival instinct developed over millennia of oppression. The best way to stay safe isn't to become friends with the country your in, friendships can be betrayed and in a world of lies it's just not concrete enough. What you need to do is to make it in the best interests of the country not to hate you.
So Jews eventually start loaning money and trying to gain a foothold in the economy. When bad times come people always blame the ones well off, the ones well off claim it's the Jews since they are also well off so they fit the bill as viable scapegoats.
