You did a lot of talking but I see no numbers showing that legitimate Engineering jobs (not those fake bubble computer engineering jobs) have left the country by a large percentage.
Do your own research. I know well the conditions of my trade and the numbers of available jobs now as compared to merely two years ago.
On "monster.com", there were 6,000 to 8,000 jobs posted at any time in my field. There are precicely 130 nationwide today. This is the same story from all sources. There are very few "head hunter" firms in business these days.
Could you tell me what I'd have to gain by making this shit up?
