> Large corporations believe anyone is replaceable.

This is definitely true. By design, large corporations are structured so that there is no single point of failure.

> Again I am an IC & don’t see/hear any extra work done for retention.

Even in large corporations, extra work definitely happens for retention (I have experienced it myself as an IC). Even though everyone is by design replaceable, the organization has some incentive to work on retention:

a) Bad retention hurts the organization's reputation and future hiring (horror stories spread very fast)

b) Within the team, losing a great teammate hurts morale and output and managers know it will result in a hit on their metrics at least for the next half.

c) Managers may not always be able to backfill, and losing an employee can reduce the size of their "empire" that they are often trying so hard to establish at whatever cost.

There's also a constant tension between using fear as a motivator to squeeze more work out of employees, but not squeeze so hard that they quit. Different companies find their own spot on this continuum. For example, Amazon is famously in the sweatshop part of the scale and they could care less about their reputation. They seem to be doing OK though.
