I selected a successful example of an attempt at a sovereign wealth fund (in fact the only example that I know), and an example of a country that chose not to implement a sovereign wealth fund despite being the same situation. I'm not entirely sure if the examples I chose constitute a fallacy. I was merely suggesting one approach that could work for some countries to establish equal funds for their citizens. Some countries may not have access to abundant raw resources though.
