The functional economies pump out vast amounts of greenhouse gasses and we are to blame the dysfunctional economies/governments for being subjected to the results.
GHGs which have greatly improved the lives of everyone in the world and are well worth the cost. Do you really believe the 'pearl divers Micronesia' don't use any technology whether it is cellphones, TVs or ICE powered farming implements? In fact, your example is quite ironic given the fact that pearls are worthless without access to developed country markets.
The problem with the blame game is it just gives people excuses for taking responsibility for their own actions and choices.
