The sense of brotherhood with your ethnic kin through a mutual shared awarenes of an esoteric spirituality & genetic ancestry spanning millenia will rub off on all but the most defective individuals and make stealing from the State that perpetuates that Mentality more taboo, hence Ethnocentric Jews rip off Gentiles more often than Jews and hence conversely why Individualistic Westerners rip off one another via Commerce & Liberalism. Each other nation lies somewhere between these two extremes.

The question "how does lack of religious and racial awerness make people abuse social programs?" could only come from a Westerner deluded by 700 years of Catholic and 300 years of Protestant Lib-Judaic, Individualistic, Multicultural pseudo-spirituality which has destroyed Faustian Man's descendants' sense of collective unity, of his ability to see his ethnic-kin as brothers; a part of an organic whole spanning the millenia of which he himself is just a link in an inter-generational chain of biological descent; these paradigms have succeded to such an extent that Modern Man no longer even sees the utility of Racial & Religous Awarenes.

Catholic/Protestant Lib-Judaic, Individualistic, Multicultural pseudo-spirituality is the father of Faustian Man, who forsakes a hollow religious faith for faith in Science; not reconciling the two harmoniosly but replacing one with the other. He spawns Modern Man, with all his superficiality but inheriting the same drive to reach for the unattainable (read: unreasonable).

In Pagan times, the East vs West European dichotomy was redundant because Germanics, Slavs, Greeks and Latins were spiritually similar; all had a healthy view of nature, man within it and themselves as indviduals forming an organiz whole. The more intelligent ones pondered this concept in Cosmic terms and created pagan religion.

The Egyptians experimented with Monotheism at the start of their degenerative period. Then came the Hyksos from Anatolia, a hybrid of Semitic & Indo-European pirates, from them emerged the proto-Hebrews who took over monotheism from the Egyptians; Moses created Judaism to accomodate a nomadic merchant-people. To gain influence , they watered down their religion, made it multi-cultural, whereas Pagan Religions were Ethnic; they called it Christianity after a false Jewish prophet & sold it to Greco-Romans at a time when their civilizational decay was at the begining of its apex and people were most receptive to dumb, contradictory ideas.

The Greeks and Romans converted the Germanics, Slavs, Balts and Altaics & until 1054 AD there was still a spiritual unity among Europeans and no meaningful East-West dichotomy could be established but after 1054 AD, the church split into Catholic and Orthodox. The Slavs and Greeks evolved the faith into Orthodoxy, formatting Pagan Greco-Slavic Pagan concepts with a Semitic theology, having inherited a decayed Greek civilization where RITUAL contrasted to LEGALITY, whereas the Germanics, Latins, Balts and Altaics started from decaying Late-Roman inspiration which in contrast to the Greek was more literal, legalistic, dualistic and generally micromanaged and from this RIGIDITY, they derived Catholicism, which is a multi-cultural Church, whereas Orthodox Churches are ethnic-based congregations, Greeks were not the ruling people of Rome; it was the Latins and because of this the Latins retained a Multi-cultural vision of Church organization that the Greeks did not concieve when creating Orthiodoxy in which each Orthodox people has its own 'pope'. Germanic Protestantism takes Catholicism to its next logical step.

A century after the Schism of 1054, Europeans no longer shared a same spirituality and they'd been growing apart for 3 centuries prior to the split thanks to the different forms Christianity took due to the factors listed in the above paragraph. Westerners gradually lost their sense of ethnic kin-ship thanks to those factors.

PS:
RE: jewish christianity:

the idea backfired; Jews would not accept this as a viable group strategy; they wouldn't convert, thus couldn't control the clergy and Christianity laspsed into anti-semitic theology, thanks to no significant Jewish participation in the running of the church. Jews had to be forced into it by Gentile monarchs who didn't understand the essence of what Christianity was meant to be, like in Spain during the Inquisition where many Jews did convert & were first welcomed by the State but when the monarchs saw the Jews were running the state to benefit Jews one-sidedly, the Inquisition became internal, as conversos were rooted out of clergy & congregation.
