It is already reflected very highly. One needs only look at the stratification of classes in the bay area to see that.
Do you really think that further stratification is needed?
If you think a junior developer fresh out of college knowing a bit of javascript is in any way comparable in terms of the value they deliver then you're wrong. Simple as that.
If you think programmers doing actual work in all sorts of businesses bring less value than bureaucrats hiding in quangos, I don't think we'll ever be on the same page.
But these arnt particularly good jobs. Programmers often have the grades to go into professional services and finance. Those jobs start at 32k.
Very few programmers start at that level.
