She delivers less (absolute) value per person, but because of the way the business model works, she can reach more people. If I build a local website and sell access to it for $10 in, say, Monaco (population: approx. 38,000 people) then I'll be making less money in comparison to the same situation but where the entire US is the market for said website. The sewer treatment plant workers don't matter to me, unless I'm living in the town where this stuff is going down. If I'm not however, those workers have zero value to me.
