It's the upper hand in certain regions. Last I checked Apple has majority market share in Japan, think it was 60% or more. Google definitely stand to lose something and clearly its worthwhile if they are paying billions per year.

Didn't President Trump also say he wanted to mandate paying H1B's the same you would an American? Seems like that would get rid of a lot of the abuse.

The current system causes trouble for a lot of people in many fields not limited to tech. Some friends have had trouble getting a residency while Indian nationals who come in on H1B are favored by the Indian doctors who deal with hiring at the hospitals they did their clinicals at in NY.

That is already the case, but only nominally. You can't hire someone into the job from abroad and pay them less. Hence the futzing with levels and job requirements and hiring "junior" employees who aren't junior at all.
