There is no one "root of all evil" in software development. Design is hard in many ways. People tend to underestimate the intellectual and practical difficulties involved in building a significant system involving software. It is not and will not be reduced to a simple mechanical "assembly line" process. Creativity, engineering principles, and evolutionary change are needed to create a satisfactory large system.

To many managers, getting rid of the arrogant, undisciplined, over-paid, technology-obsessed, improperly-dressed etc. programmers would appear to be a significant added benefit

Certainly not every good program is object-oriented, and not every object-oriented program is good.

Too many managers and executives try to reduce programming to a low-level assembly-line activity. That's inefficient, wasteful, costly in the long run, and inhumane to programmers.

Some software is actually pretty good, by any standard. Think of the Mars Rovers, Google, and the Human Genome Project. Now, that's quality software!

Nobody should call themselves a professional if they only knew one language.

C++ is designed to allow you to express ideas, but if you don't have ideas or don't have any clue about how to express them, C++ doesn't offer much help.
