I agree that eggs and poultry are the best things to remove from a diet from an ethical perspective, I just thought that promoting veganism isn't a good idea. Most people won't go vegan anyways, and it's overall better if we get everyone to go flexitarian rather than a small minority going vegan.
It’s not strictly relevant, but the Word Bank publishes the Doing Business Report, ranking countries based on how easy it is to do business. Some indicators might be useful to charities, too, like enforcing contracts. Maybe, on average, countries with higher ease of doing business have also higher ease of doing charity.
