The contrast that you describe between the state of spirit of sysadmins vs. programmers seems to mean that programmers do not need to consider impact on the rest of the architecture and the long-term maintenance cost of any given code change.

The programmer you are describing are a kind of programmer who makes lousy programs. I've read enough of those programs to say: they are not pretty -- they do not work well in large scale -- and they cost a LOT.
