What is the poverty over the Jews?

> They have been put under humiliation [by Allah] wherever they are > overtaken, except for a rope [i.e., covenant] from Allah and a rope > [i.e., treaty] from the people [i.e., the Muslims]. And they have > drawn upon themselves anger from Allah and have been put under > destitution. That is because they disbelieved in [i.e., rejected] the > verses of Allah and killed the prophets without right. That is because > they disobeyed and [habitually] transgressed. (Ali 'Imran : 112) Why, if there is poverty above them, did many rich Jews live and live in the world? Furthermore, the economic situation of Jews has improved significantly in recent history. As a related question, are today's Jews to blame for the murder of the prophets and does this affect the poverty that Allah has placed on them?
