It's because that 1 micro-service has 300 dependencies.
Higher levels of abstraction makes it easier to get something up and running fast, but at some point you need to be able to look under the hood and understand what's going on, and many programmers today can't do that.
That being said I think the drop in average skill is mostly a product of the growth in the number of programmers. I imagine that if the ability to sculpt a basic statue suddenly became really valuable, the skill level of the average working sculptor would plummet.

More layers of indirection in a system and more dependencies on external libraries and tooling does not necessarily get you any abstractions. To take a contemporary example, there is no "abstraction" in being driven to use Docker because your dependencies have gotten unmanageable otherwise.
No it's not. OS-level virtualization is the abstraction. Docker is a set of tools to manage Linux containers and virtual filesystems. You can argue that libvirt is an abstraction because it does actually work over several different virtualization technologies.
