When a large tech company starts to fail, there's a real downside regardless of how we feel about its product. People lose their jobs. Often, thousands do. Many of these people then find themselves having to move to another state or country to continue working in their chosen field.

But there's an upside as well. A large layoff means there are plenty of qualified workers who are looking for work, and what better way is there for a company to acquire hot talent than to move to where the people are?
