Each nation with the increase of Jewish citizens become wealthier

[Myapologies]

There's a tendency in history that each nation where the Jewish population had it's peak became wealthier, because Jewish merchants made the economy process faster due to their good sense of business skills. When the Kings became jealous of the Jewish wealth they've managed to ban "trading" or tax the local Jewish population therefore they moved to a new country, but the same time the ex-country of Jewish presence became poorer.

The Spanish and Portuguese kingdom has risen when it had the highest population of Sephardic/Marranos who managed most parts of the economy, by lending money to kings and manage foreign relations which covered most parts of the world.

Today USA has the highest number of Jewish citizens and see how nearly half of the American wealthy class is of Jewish ancestry.

There maybe a relation sometimes. At least in the past 500 years in the Western world.

To counteract that, Poland and Russia had lots of Jews, and they didnt become richer from that really.

What is more accurate is the influence of Jewish bankers elites. 150 years ago in the US the Jewish population was smaller, and it was already one of the richest nations.

(we can debate about what "wealth" is, cause argument can be debt isnt wealth... it also happens the countries with lots of debt happen to have Jewish elites).

Outside of Europe, Japan, SKorea and now China have close to zero Jews and they were or are becoming wealthy.
