So my view of the layoffs at the big "IT Vendors" is simply that the tasks which they originally hired workers for became increasingly automated or moved to systems that were less labor intensive.

A lot of the workers in India, for one example, worked on things you would hardly call programming. e.g. creating charts from data, manually moving data from db to db etc. These kinds of tasks should have (IMO) been automated in the first place, and should not require full time employees to handle them. As the automation become more mature, stable and well adopted, the bigger vendors start using them and don't require fleets of humans to manage them anymore. For a concrete example, I think ansible (and related tools) probably "destroyed" thousands of jobs as you didn't need to manage bash scripts manually etc.

There is another fleet of people who are hired simply for maintaining, developing on legacy systems, people you wouldn't find in the US. e.g. COBOL programmers.
