H1B is a significant problem, but so is offshoring. From a business point of view, the cost savings are too immense to ignore. If you can pay a foreigner $5K to do something an american workers does for $50K and pocket the $45K annual difference, it's a no-brainer to corporate executives. The shareholders will benefits and the C-Suite will benefit, the workers will suffer.
There is a reason why the leftist and rightist establishment are working so hard to get hilary elected. The amount of pro-Hilary propaganda on NPR, NYTimes, LATimes, etc was nearly unbearable while she was fighting against Sanders. Now that Sanders is done, I might have to stop consuming these media for the next few months.
As much as we like to pretend, there isn't two parties. There is one party ( the elite ), that control both parties to gives an illusion of choice. Even the republican establishment are trying to undermine Trump to give Hilary the presidency.
Complete protectionism/isolation isn't a good thing. But extreme liberal trade policies aren't a good thing either. Thought maybe Trump will get the nod and push policies towards the center, but there is too much money at stake for the elite so they are going to force hilary, TTIP, TPP, etc on us no matter what.
We are going to replace one corrupt chicago politician with another.
