Engineers, and others too, can become obsolete fairly quickly and thus are unable to reenter a technical job.

As a senior I've had to change careers several times. http://www.geocities.com/computersystemsdocumentation/bill5g.htm

What is bad is having to discard lots of knowledge you worked hard to learn [like the IBM 360 assembler programming]then having to devote time to learn new stuff.

Iran War Warning - Thursday, March 09, 2006 @ 1:35:28 AM

In the nuke confrontation, Iran is indifferent to the UN sanctions because it already is a nuclear armed power and is eager to demonstrate its fierceness in confrontation or in a strike-counterstrike scenario.

Iran wants oil at $80 to $100 per barrel. At the same time it is hurting the dollar by selling oil at a discount on a bourse in Tehran that accepts Euros, not dollars, for oil. Iran is cocky, apocalyptic, resolute, cunning, disciplined, unafraid of martydom. It will not climb down from the fight. It will challenge the U.S. with words and deeds; it will not surrender.

Consider this a war warning. Not weeks, not months, no certain timetable, at a time of Iran's choosing.

We've even had to make a career switch into law!

Selling at a discount may be the part that could really undermine the USD.  I often get the feeling lately that Mideast instability is exactly what the US wants, in order to keep the price of oil up.... know what I mean?  ... I mean that EVERYBODY in Washington can't be as stupid as I think they are.  There has to be some continuous thread underneath all of this.
Wait, wait wait.

First I thought the bourse is opening on March, 16th.
Second it is ridiculous to think that selling with discount of your own oil will hurt the dollar significantly. The bourse would be a threat only if it would offer market to other players, wanting to sell oil in euros.
Third I did not know that Iran is attacking USA... sounds absurd to me. They may be provoking the hawks here to go in the trap of attacking them, but this is a whole other deal.

I think there is a whole bunch of people trying to present Iranians as suicidal idiots, ready to die until the last person, in order our gas to be 10$. I don't buy that.
