I am not sure how viable this hiring model is for companies that want to develop bleeding edge IP. Speaking only about development jobs: contractors are nomadic, they're not tied or married to your success or failure. From a developer POV, that's not a bad thing. You can just come in, do your thing, and move on to the next great adventure. From the employer side, each time you are training someone new to become familiar with your code base, your company intricacies and peculiarities, etc. which takes time and effort, and learning from failure, time for which may not be available. And the end result is that you may end up with a mish mash that doesn't work well together because the people who made it are gone or moved on. Also, developing is mentally exhausting. Not sure what dev, unless they're really desperate, will want to indulge this and expand that kind of mental effort for less payout or benefits. Or maybe the company only hires these for less innovative stuff or CRUD jobs.
