Outsourcing has ensured a downward pressure on salaries. Can an employee that is not allowed to leave his employer really ever going to be earning true market rate on salary? That's the case for HS1B in the US. There is plenty of evidence that salaries are manipulated down. Now, regarding your proposed solution of becoming a master of rare and difficult skills. That's what I strive for, but that can be a challenge in an industry where technologies are replaced every 5 years or so. In reality it becomes that much harder because unlike other professions the mindset of employers does not respect the concept of 'superstars'. Ie. I can't really name a developer that has the ability to command a 50% premium over his peers. However, I can name several companies that can demand a price premium for their consulting services. So, how do we as a field make the shift from companies achieving a price premium to individuals achieving a salary premium?
