The H1-B visa is intended for bringing specific technical expertise that does not exist in the US for a set period of time. This is why one of the requirements is that you must have interviewed US persons first. Its the same reason it's a nonimmigration visa.
The rampant abuse of the visa has a remedy - criminal charges against the HR directors of any company who is found to have committed fraud, and capping the number of visas per company (setting up many shell companies is a strong signal that fraud is being committed).
If an H1-B worker can't negotiate on a global level for their expertise - they should not be on that visa.
