Compare GTK/Qt to raw xlib/wayland/win32/cocoa primitives - including the way that those toolkits abstract away the differences.

Or (as others have pointed out) the various `git` "porcelain" commands (checkout/add/commit/branch) compared to the primitive operations for dealing with various object types. Even just `git pull` as a combination of `git fetch` and `git merge`.

Or how a filesystem API of open/read/write/close/unlink is a very simple abstraction over block allocation and (in the old days) moving a disk head and waiting for the platter to spin under it in order to access the right sector. Not to mention the "directory" and "subdirectory" abstraction, instead of just having one giant table of inode numbers.

Edit: Or compare HTML with abstractions like "headings" and "paragraphs" to a raw typesetting language like troff or TeX.
