This is really an issue of price points. If companies went around offering contracts for double-current-salary, full benefits, and guaranteed employment for 5 years, positions would be filled fairly quickly.

If the required price point is higher than a company can afford, maybe key goals, plans, and roles need to be reevaluated. As I say to my coworkers all the time, software project estimates are not very accurate, so if business will die without 10% returns on their software development investments (or being within 10% of schedule estimates), everyone's already in trouble.

That's highly dependent on the problem domain. Again, perhaps those are in demand because companies' expectations aren't keeping up with market prices.
