Let’s begin with the facts described in “Study: Ashkenazim in Israel earn 30% more than Mizrahim, 61% more than Arabs” at:

The post says:

“In an urban setting, the monthly income of the average Ashkenazi salaried employee living in a city was 12,950 shekels per month, which was 42% higher than the urban average, while the average Mizrahi Jewish urban salary was 9,970 – 9% above the urban average. … Findings show average Jewish Israeli earned 9,721 shekels in 2012, while the average Israeli Arab earned 6,029 shekels.”

So an Israeli Ashkenazim earns more than an Israeli Mizrahim and both of them earn more than an Israeli Arab. Of course, the individual earnings depend on many factors such as education, skill, general economic situation, discrimination, and even person’s character. However the post evaluates the disparity in earnings of large groups of individuals and therefore a search for a sort of group identity that may influence the earnings is justified. The groups’ identity can be describes in the following way.

Ashkenazim Jews are Jews of Central and Eastern Europe who have lived for almost two millenniums in the Torah-based Judeo-Christian spiritual environment in Christian-majority countries.

Mizrahim Jews are Jews who are descended from local Jewish communities of the Middle East who have lived for over millennium in Sharia-based Muslim spiritual environment in Muslim-majority countries.

Israeli Arabs are Arabs of Palestine who have lived in Palestine for about thirteen hundred years and who created the current Sharia-based Muslim spiritual environment.

From this groups’ identity the disparity between Jewish population, Ashkenazim and Mizrahim, and Arab population is obvious.

The majority of Jews are creative since they feel – consciously or unconsciously – they are made in the image of God the Creator as the Torah tells us. This creative trait is distinguishing all the Jews including those who even consider themselves non-religious. The creativity is needed to make more money and have higher earnings. To make more money you have to sell more goods or services. To sell more goods and services you have to be more creative than your competitors. A more creative group of people produces innovative goods and services less expensive and with better characteristics.

The majority of Arabs are less creative and innovative since Quran and Sharia emphasize the virtue of life in the havens – not the virtue of creative life here on our earth before going to the heavens.

The disparity of earnings between Ashkenazim and Mizrahim it looks like is based on completely different social and business environment these two groups historically lived in.

Ashkenazim have lived, before moving to Israel, in the Torah-based Judeo-Christian spiritual environment in Christian-majority countries where the creativity was generally appreciated (of course, not always for the Jews). The Judeo-Christian environment let the Ashkenazim Jews obtain much better competitive skills than Mizrahim Jews obtained in Sharia-based Muslim spiritual environment in Muslim-majority countries where the creativity was subdued to follow the guidance of Quran and Sharia. And that is why in Israel Ashkenazim’s earnings are higher than earnings of Mizhahim Jews.

The difference in earnings of Ashkenazim, Mizrahim and Israeli Arabs is not a result of discrimination – it is the result of spiritual beliefs (Torah vs. Quran).
