Skills sets are progressive. You can’t have an economy that just has top level skills and jobs.
Well, you can, but that only works for a generation.

Well, you don’t need everyone to have the top skills. You just need enough people in your country to have the top skill to justify having a presence here at all, so the rest of the people who aren’t top level skills can be supported locally with local wages.
Building a damn is also slightly different. The work literally has to be done here, unlike building a portable product or service. Different set of rules.
