I think its all a bit more complicated than you describe here.
True is, that Jews have been over average successful in business. But I doubt that its a matter of intelligence. One key factor is, that Jews have always formed closed communities, inside which they supported each other. That is a good receipe for success, if other people act as lone wolfs and make each other's life difficult. That has sometime led to envy, anti jewish resentment and even open violence.
Another factor was the bible and the catholic church. In the bible its the jewish who were responsible for the death of Jesus. And since the vast majority of people since the early medival time were catholics - often to a level of mental illness - there was always a furtile ground for distrust, or even hatred, towards Jews.
But the issues with the Jews taking over Palestine are even more complex. There is certainly no visible intention (by the British, who ruled Palestine at the time) to prepare a homestead for the Jews. Its a long story, and I recommend that you read up on the developement of the Zionist movement beginning in the late 19th century, until the founding of the state of Israel in 1948.
To make it clear: I am also opposed to the current conduct of the Israeli government. Its very disappointing to see how they, of all people, treat the Palestinians as a lower lifeform. That is just as unacceptable as it was when the Germans did this with the Jews during the Nazi era.
On the other hand, I can understand that the Israelis are scared. For one because of their history, but also because they are surrounded by enemies (more or less outspoken ones). For them, there is no plan B to holding what they have now. Even if the explaination that this was the land given to them by God some thousand years ago is more than lame.

But things are as they are. If all the historical wrong doings would be reversed today, the world would end in total chaos. The only thing we can do is, to avoid more of this nonsense in the future.
