"Really? Amazon is going to import 50,000 people? That is a ridiculous comment"--We're already supposedly experiencing a labor shortage for all kinds of jobs here, not just the high-tech ones.  Where do you think Amazon's going to find 50,000 people to fill them?

"It sounds like you need to improve your skill set if you are concerned that an influx of high-tech jobs will relegate you to a career in a strip mall."--Yeah, we can all become coders (that will be replaced by H-1Bs and outsourcing at the next economic downturn)!  

"Those Amazon jobs will pay for themselves"--All the growth we've had over the last 30 years seems to belie that claim.  Not to mention even MORE people in an area that has low housing inventory is going to increase housing costs even more.  You really want Denver to become like Silicon Valley, where people making $100K a year are living in garage spaces?  That doesn't sound like "opportunity" to me.
