the things people do and still get paid

The programmers who are paid well and get promoted while being completely ignorant of the implications of a package name for a Java source file. While it seems stentorian to expect everyone to read the Java Language Specification (Chapter 7, in this case, and section 7.2.1 to be precise), it surely isn't too much to ask that people heed the complaints of javac when it fails to successfully compile files whose package names have nothing to do with where the file is located on the disk.

The programmers who flaunt experience with the newer versions of the JDK (5.0 and 6.0) on their résumé but ignore javac's warnings about all the raw types abundant in their freshly written code, simply because they do not understand why the compiler has a problem with code that works.

The programmers who just don't understand why XSLT (from the wikipedia page: XSLT (XSL Transformations) is a declarative, XML-based language used for the transformation of XML documents...) does not work on a document that is not XML.
