I was interested to learn that the Amazon deal in Northern Virginia came with an educational caveat / commitment:

[The] final deal with Virginia includes a commitment to build a $1.1 billion Northern Virginia Innovation Campus for Virginia Tech University with a mix of graduate academic instruction, research and development facilities, and space for startups. This campus should not only serve Amazon’s workforce needs but also create a pipeline of skilled workers for other local businesses. That means the plan could benefit the local economy even if Amazon does not create the full 25,000 jobs it promised or even if nothing Virginia offered actually influenced the company’s location decision.
