"Every H1-B visa is an opportunity for an American business to bring a product to service to market at a lower cost with a better chance of success."
Accurate translation: Every H1-B visa is an opportunity for short-sighted American managers to screw their own employees to bring a sub-standard product to market at a lower cost, while the few young Americans who still think about entering these skilled areas bolt for whatever jobs aren't yet seen as ones where employees are expected to work 20% more than the average for 20% less pay.
I tell ya, I've been working alongside these types for 5 years now and maybe, maybe 1 in 10 produces reasonable work. The other 9 put in lots and lots of hours and look so very productive but produce shoddy work on top of the fact that for all their vaunted knowledge they have a command of the English language which makes publik skool students laugh and therefore do not really understand what it is you want of them or the assistance you gave them for the sixth time this week.
H1-Bs are the employment equivalent of buying a Yugo. Sure, it's cheap, but so? "So" means nothing, though, if you produce fictional ROI as a manager and bug out to a new job and promotion before it's time to assign blame for the defects.
Oh yea, AND the real engineers out-produce them by factors of 5:1 to 10:1 notwithstanding the quality issue.
As thoughtomator alleged, they're functionally lazy. They're AT work at all hours but that doesn't equate to producing anything.
