True, you can’t dig a trench valuable enough with kW/hr output to generate a billion dollars in value.

You can, however, come up with an idea that improves the lives of 1 billion people by $10 worth. It turns out that ideas are more important to improving the state of humanity than kW/hr output of hard work.

You may be arguing that being one of the billions whose life was improved by $10 is ‘others doing it for you’
