In the end all of the components in this model point in one direction: if trust levels are diminished by any combination of factors, poverty will be the result. If trust levels are enhanced; higher levels of prosperity will follow. Linguistic diversity can lead to lower trust levels if it leads to the conclusion that "I can't trust those people who use a different language." Linguistic diversity is an 'in your face reason' to make it difficult to extend truth. Fear is the ultimate killer of inter-group, inter-region, inter-community economic exchange. Shared beliefs (my chosen truths) leads to the desire to extend trust to those who claim to adhere to the same chosen truths. OR: the level of 'extending trust' is proportionately higher within a community that upholds the same chosen truths than between communities that do not uphold the same chosen truths. at the same time: some religious belief systems in combination with their cultural expression do not naturally teach their followers to extend trust to others but rather teach that trust is always earned (eg: this is why inter-region trade in the Middle East is lower than anywhere else in the world).
