1. We want to drive down wages in the US
Rationale: Wages in the US are high compared to the rest of the world. To sell to consumers and customers in the rest of the world, US wages must come down.
2. We prefer to import H-1B's. Opening offices in other countries is not as efficient as bringing skilled people to the US where employers have the upper hand.
Rationale: The US is the only developed country with 'employment at will' This is preferred over 'just cause' used by most of the rest of the world. By importing H-1B's we get the business-friendly legal framework, and we can deport any troublemakers back to thier home country if they rock the boat. Opening offices in
other countries is costly and requires a management to be present in the offshore country, and the timezone differences hamper productivity.
3. The US federal government is one of the few in the world set up to put the interests of the 'opulant minority' ahead of the common people.
Rationale: We can pay lobbyists to promote laws in our interest knowing that we will get favorable laws passed which are not popular with the US electorate.
