Agreed with the harm to locally-made innovation. In my city (Fredericton, NB) the tech industry has hade (seemingly) more and more bigger companies (Raytheon, Siemens, Salesforce, IBM) setting up shop and bringing better wages. It's a double-edged sword. We have a pretty interesting startup scene, but those smaller companies (startups and consultants) are now finding it harder to compete with the salaries and benefits the large companies can offer.
That's the only way to really drive salaries up though. Which is the only way to retain talent when it is so easy to cross the border and start making a whole lot more.
