Many have attempted to link economics and religious doctrines and have met with exceptions and better explanations. During the Ottoman and also some Post- Ottoman era and places, both Christians and Jews did quite well businesswise. This does not imply that the Muslim majority were backward economically. Teachings and rules dictated how things were run. Owing to the fact that the top ranking military and public service posts were not open to non-Muslims, they resorted to businesses as a means of making ends meet.
The same applies when you think about Greece’s economic misery. It does not take a genius to see the connection and similarity between Orthodox Christianity and corruption/cronyism in the sense that all are somehow charitable towards human weakness. Orthodox Christianity has a more optimistic view of what it refers to as “original sin” compared to their western counterparts. When they pray for the dead, their emphasis is on, “no man lives who does not sin”. Question remains, is that meant to fuel the sin fire? Maybe—but the Greek-Americans are not having any of that. The more plausible reason rests with America’s systems which make it far much easier to prosper in an honest manner.
An American sociologist by the name Peter Berger had this to note. Protestant communities tend to mostly preach prosperity especially African and the Latin American Pentecostalists . This individualist Prosperity gospel is more popular there than that of liberation of poor souls which is preached in the Catholic Church. This is because prosperity attributes financial success to divine favor.
Religion is made up of complex belief systems which not all may be desirable to everyone. Human beings therefore tend to emphasize the beliefs that are deemed most convenient and appealing. Take the example of Turkish traders who like parts of the Koran which are in favor honest to God trading.
