Big tech can get waiver from DHS.

Cheap labor exists because there is a demand for it. Body shops don't pay those wages - companies who hire those bodies from body shops do. So, body shops are going to raise prices accordingly.

"You need someone to manage your Oracle/SAP ERP systems and do a horrible job of it? And that person needs to be here locally? That will be an extra $60k from our last contract because we cannot bring in cheap bodies now." (assuming they eat $40k of the costs)

In the meantime rural medical centers will be devasted because many teams are made of H1B doctors.

H1B certainly requires more government oversight. But doing their jobs or applying critical thinking skills isn't a criteria for this administration.
