It’s going to be more expensive to hire and train new people when the dumdums in upper management finally figure out the mistakes

Unfortunately that’s not the case. Those who have been laid off are those paid high salaries to build up the foundation. Now that the foundation is already there, they future work won’t be as complex as before and need less training. So why would they still pay the very high salaries? They’ll just get rid of the used-to-be-important programmers and hire the can-be-hired-for-a-lot-less programmers from India. It’s sad, but that’s the reality.
