Actually I meant that most skills would be of use to some charity, not a particular charity. Certainly there are some skills that are not of value to any charity I would support.

To further clarify, I am considering charity to mean non-profit enterprises whose purpose is to benefit more than their own contributors.

Too many courses on population models have led me to believe that resource availability has to climb a steeper curve than population growth for sustainability. I am not certain that short term support for individuals living in inadequate conditions is a net positive. Cultural standards particularly regarding family size are difficult to alter. I choose to apply my efforts to a different set of problems.
