There is no true Left in the US, just as there is no true Right, both sides of the isle are defined by the interests certain groups having joined one side or the other over the history, instead of by ideology. Thus in both sides you can find conflicting beliefs to the supposedly Left or Right ideology that they adhere to. In the Democrats case is the support for large Tech and Hollywood business (coincidentally? based in California) while in the Republican case we believe in small/non-intrusive government except if it's about army, foreign policy interventions and people's sexual behaviors.

Wait, I thought it's Apple, Microsoft and ("especially") Google that are the good H1b players and it was the Indian Tata/Infosys/etc that are abusing it, according to the numbers at least. Care to back up your "it is a threat to national security" and "unacceptable and should be downright illegal" statements?

So let me get this straight. On one hand you say the housing prices are increasing because of an increase in high earners, on the other you say the salary of engineers is being pushed down by H1bs. Those 2 issues seem independent at best, or contradicting at worst. If the H1bs wouldn't have reduced the salary of engineers then housing prices would have increased even more as more engineers would have moved to that area (which is an independent issue from having H1bs moving to the area, they move there because local companies want to hire more engineers, being H1bs or not doesn't change that fact). Thus your post subject of "H1B visas increase housing prices" would be more accurately defined as "H1B visas makes houses prices increase at slower pace".

So on one hand "Silicon Valley abuses H1b", on the other, most H1bs aren't given to Silicon Valley companies so obviously if they abuse it, they are far from the top abusers of it, according to the numbers. Make your mind? I would also like to point out that the summary is misleading. Yes, once you are on the EB (employer sponsored) green card process, while you are waiting for it to be processed if you move employers you have to start all over (for obvious reasons since the labor certification process requires to specify skills that apply at the current position which can easily change if you move), but once approved the immigrant isn't bound to a single employer anymore. So not really sure how this is part of "Silicon Valley's abuse of H1bs" because it rather looks to me like them wanting to get these people here and have them stay permanently. Oh, you're thinking of Chinese/Russian/Indian citizens that have to wait 10+ years for the green card to be approved (which btw, is kinda insane if you think about it, people get married, have kids, get divorced, multiple times in that kind of time interval)? Well then why not try to propose something to _speed up_ their approval process and so then such people will be stuck in the EB approval waiting process for much less time? While it's true that statistically a large number of H1bs are abused (could be most of them right now) it's also true that a large number of them are being used to hire skilled talent that we want in this country, because if they are working for us here they are using their highly developed skills to boost this economy and they pay taxes for their income. The question of course is how to allow for these (or make it even easier for them) while making it hard for the abusers.
