This is a little backwards. Trust might be the cause of societal wealth. But it is also an effect of the system of laws. Americans are not more trusting/trustworthy because they are more cuddly and friendly -- Somalis probably have and deserve more of that kind of trust. The kind of trust that makes America rich is the kind of trust you place in strangers who know they are doing commerce under the rule of law. The promimse made by Bitcoin and such is to add a new component to that sort of enforcement -- increasing trust.
