“Pliable” foreign labor is a critical part of this scam.
The ultimate goal for most of the Asian Indian software engineers with H-1B visas is to obtain a USA Green Card.
In most cases they need a USA employer to sponsor their Green Card applications.
Thus, when their American employers demand high productivity and long hours, none of the H-1Bs complain.
The reality is that they get sent back to their home country, after extracting whatever knowledge exists in US-side operations.
Cheap, pliable domestic politicians begat cheap, pliable foreign workers.
