So do I, but those who build basic tools very often also make stuff for end users too, but there is a lot of programmers that only do end user software based on existing tools. They think basic tools is something someone else does, and if there is no such tool, then what they tried is "hard to do". It will never appear to them that they can make the tools themselves, or they don't have the skills to do it. The distinction is real, in that many programmers never do build basic tools, while it is artificial in the sense that there is no reason for this other than lack of skill and organizational culture that says that that is not something you are supposed to do.
