You are confused as to the nature of this conversation. YOU are the one making the claim "every H1-B is taking a job from a US citizen". Nothing in either of the linked articles supports this claim. They all talk about shortages, but not about _qualified candidates_. They are not the same. Even so, I just explained to you how in obvious ways, even if there is no shortage, your assertion can be proven false.

If your argument was US citizens should always be given priority regardless of their skill, I might actually agree with your position.
