IT jobs are pretty easy to export, too, so if there's a big disparity, sooner or later, the jobs can go the other direction, if the people can't come in this (towards the US) direction.
In practice, this depends on a number of factors being aligned correctly and an organization being tuned to the idea of remote work. Especially if the deliverable of the IT job in question is part of the core function of the organization.
Exporting with long-term net success (in savings or quality or both) is what's difficult.
