Nothing against educating girls, but this is probably the wrong conclusion. Economic situation determines whether girls can get an education or not, so educated girls correlate with a good economic situation. Not the other way round (educated girls causing a good economic situation).
Personally, I think this focus on girls only is sexist and I take care to never donate to charities that only want to help girls.
