If that were the equation, I'd be on board with that point of view. The problem is that the H1B is increasingly used to outsource jobs rather than bring talented engineers to the US. Seven of the top 10 users of the H1B visa are India-based outsourcing companies, and even many of the US-based users are really there to facilitate outsourcing. These companies use the visa to cycle someone through the job in the US for a few years, do "knowledge transfer" where an American is allowed another 6 months of employment and a severance under the condition that they train their replacement, and then move the job and worker overseas. SO in this case, you'll get your 6% pay cut and the outsourcing of an industry - all under the guise of making sure that talented foreign engineers are allowed to come to the US and create wealth (which is an indisputably wonderful thing for the US and would be possible without all this abuse if the system were reformed).
