They will come back (eventually).

Having to work with ESL contractors from firms like Cognizant or HCL is true pain. Normally it would be like 3-4 US employees working on something and then its like 20-30 ESL outsourced people working on something. The quality is so poor though its not worth it.

My current org nuked their contract w HCL after 2 years because how shitty they are and now everything is back onshore. Millions wasted lol. Corporations are so silly sometimes.

They also need 5 people to do the work of one us worker. And then another US worker to guide and do some qa on the output they produce . I don't see how it saves money. There are other countries with lower wages than the US where this doesn't happen such as Poland or Australia.

They are. Companies also do this and then wonder why they get blackmailed for terabytes of leaked proprietary data on the darkweb.

Saving money on wages isn't the only consideration.
