My appologies to those looking for discussion about the video card, but these issues need to be discussed wherever and whenever.
Postdocs -- laugh! The postdoctorate is an insult! Why would someone with tremendous productive and intellectual ability, a bachelor's degree, and a Ph.D. (at least 9 years of education, if not 10 these days) want to work 70 hours/week for less than $30,000/year ??? The very existence of the postdoctorate, at least the large quantity of postdocs, is evidence that we do not have a shortage!
[One of the reasons why I lost the drive to complete a biophysics Ph.D. in the late '90's was my concern about the employment market and a feeling that I should be using my talents elsewhere. I left with a MS and headed to law school thinking patent law. Of course, the employment market changed dramatically in just a couple years. When I started law school, a mere bachelor's in chemistry plus a JD from a second tier law school would allow one to obtain a six-figure job. Today you need at least a Ph.D. and graduation from a first tier if not a top twenty law school plus above average grades.]
Keep drinking the kool-aid. I don't buy any of it. Whenever a business or politician claims a shortage--you have to make sure that it's qualified by asking the follow-up question, "shortage--at what price?". If you're talking about companies wanting to pay low wages for college-educated employees, hopefully there will be a shortage. If you're talking about wanting to hire the top 5% of people with the needed skills at average wages, there will be a shortage, as well there should be.
A shortage is actually almost impossible, at least given the current state of our jobless recovery economy. Basic principles of economics tell us that when there is a shortage, the price point will have to increase and that when it increases, more suppliers will enter the market to fill demand at the higher price point. In other words, if job opportunities at upper middle class wages with job security were going wanting for applicants, students would rush into the field (and people would go back to college to rush into it). This is where many of the now laid off IT people came from (rushing into the field during the '90's).
I laughed when I saw you talk about postdoctorates! Postdocs are low-wage gypsy scientist positions and the only reason people with 9+ years of college education take them is because they cannot find better jobs (either as academics or industry researchers). The very existence of postdocs suggests an oversupply of Ph.D.'s. (This has been public knowledge for some time. Even Science published a short article about a glut of physics Ph.D.'s a couple years back (something like 1470 newly awarded physics Ph.D.'s and only 42 jobs for them in a certain recent year).)

If we have such a shortage of skilled, college-educated people, then where are the jobs for them? How come newspapers aren't chock full of large ads? Where are the radio ads offering to give away cars to engineers who submit their resumes? (I heard them on the radio years ago.) Until just a few months ago the economy had suffered a net loss of private sector jobs under the Bush regime (with the small net gain being created by the growth in government). Not only has this been a jobless "recovery", but in terms of jobs per capita, we've suffered a large loss since the economy needed to generate about 150,000 new jobs every year to account for our nation's runaway population growth (32.7 million in the ten years from 1990-2000). In other words, over the past four years the economy needed to generate at least 6.5 million new jobs just to keep pace with population growth.
Remember, when the corporations claim a shortage, they are really just asking the government to increase the pool of labor so that they can keep a larger percentage of the value created by the act of production for their own profit. It is very short-sighted since this kind of labor wage arbitrage will end up damaging the nation's economy. [It's short-sighted because the businesses won't be able to keep selling their products at the current prices when the populace no longer has the money to purchase them at those prices. But it's similar to a tragedy of the commons--the costs of the actions are externalities and if you don't take advantage of the commons (foreign poverty), your competitors will.]
Take the businesses' claims of a labor shortage with a rock of salt.
When I start to see news reports about how the nation's economy generated 500,000 new jobs per month for the past six months and how the majority of them were full time solid middle class and upper middle class jobs (as opposed to a mass of worthless poverty wage retail service jobs and temp jobs) then I'll believe that we have a shortage. When I can easily obtain interviews and find myself competing with a mere three other candidates (as opposed to fifty or three hundred) and start to receive a number of offers with my being a mediocre interviewer, I'll believe it.
Based on all of the evidence that I have observed, we have a large oversupply of college-educated people, including those in technical fields and those with advanced degrees.
I guess much of it is based on people's perspectives. If you did well during the recession and if you're a naturally good interviewer and the market was good for you, then for you the economy is really good. It's self-affirming to buy the propaganda the politicians and media feed to us, especially the ever-popular education-shortage myth. (Why Americans gobble that garbage up, I do not know.)
When you read the articles about the number of new jobs created every month, ask yourself:
Is it enough to keep up with the population growth of the labor force (at least 150,000/month, not counting the growth in illegal aliens)?
Will it be enough to make up for the jobs deficit that the nation suffered over the past couple years when we either lost jobs or didn't gain enough new jobs to keep up with population growth?
What kinds of jobs were created and at what types of wages? Were they full time college-education-requiring high-value-added jobs, or were they temp jobs and poverty wage service sector jobs?
Sadly, our near worthless media doesn't ask those kinds of questions.
