Or if the job is an outsourceable one that can be provided as a service then they will outsource it to a company overseas and still pay peanuts. The only reason they'll raise wages is if they have to, aka the service cannot be done elsewhere or automated.
If your company doesn't need domain experts/doesn't change to the point these people can be remote... you are a zombie company and will be replaced by someone that does utilize domain experts/dynamically changes all the time with conditions. Even with just a factory, when I moved from dev to IT, getting my people to understand our users by going out to the floor and sitting with people we were able to greatly improve efficiency in a way no remote IT could.
They already are... Generally insourcing is to reduce the friction of doing so, because application managers and product owners don't want to relocate to the countries they're doing the outsourcing with.
A lot of jobs require or are better done on-premises, which is why they hire H1-Bs. Outsourcing is already cheaper, by far, especially if you want to go to the third-world.
