Big Tech should be locating large employment centers in strategic locations around the country. And by strategic I don’t mean where the talent, resources, or customers are located but rather where influential Congresspeople, Senators, and Governors are located.

Initially the only way from the bottom to the surface is around the edges. But as the ice crust weakens, you start to be able to punch right through the middle.
The edges of the pond were pure tech: companies that actually described themselves as being in the electronics or software business. When you used the word "startup" in 1990, that was what you meant. But now startups are punching right through the middle of the ice crust and displacing incumbents like retailers and TV networks and car companies.
So you are right in saying that in a world of starvation rich people should be an aberration. That is to be expected.
