A calculation of effectiveness should contain not just an assessment of magnitude but also of scalability.

Most people can't become Bill Gates or Elon Musk. There's not enough births of the computing age, or births of online banking to go around. There's a lot of people seeking to do social good within the confines of capitalism.

So while most (all?) techniques may be less impactful than Gates and Musk, we shouldn't hold back people trying to find other strategies (dare I call them entrepreneurs) by confining them to being ruthless capitalists who later grow benevolent or build Wayne Industrieses.
