See subject: It is a LARGE margin & suddenly when what YOU yourself describe is used against you it's now "irrelevant"?
You have misread. What is irrelevant is (1) general ed - The MBA student has already taken their general ed, they already have a Bachelor's degree. (2) minor - any minor outside of BA is not on topic, matter of fact that is a loosing path for you to go down. Few BA majors seek minors while all MBA candidates already have a full Bachelor's. About 1/3 in scientific or engineering disciplines.
Not only can I speak of Business degrees (having one myself, a FULL one no less up to Bachelors level) but I also can of CS & DATASTRUCTURES is one of the VERY BEST MOST INFORMATIVE COURSES IN THE CURRICULUM
I'm afraid your appeal to authority is not going to work here. I have Bachelor's and Master's in Computer Science and an MBA. Plus about 30 years of software development experience, except for my Freshman year working while in school for all three degrees. Data Structures is absolutely critical, however an intro to data structure type class will not be revisited in a Master's program. You are expected to go pick up Knuth or equivalent on your own if you need info on the mechanics of implementing list, trees, graphs, etc. Such basics are not worth the class time in grad school. These are things you are assumed to know by the prerequisite of a Bachelor's. What will be revisited and delved into much deeper than undergrad classes is analysis of algorithms. The time and space complexities of algorithms is appropriate for grad school, not simply basic coding of implementation details.
Similarly various electives of the undergraduate BA program are not appropriate for grad school, the MBA program. These classes often represent topics that are appropriate for students who have never had a job in the real world, entry level positions. They would be a waste of time for someone who has years of experience in the real world and has moved beyond entry level positions. Such classes are the primary difference between an undergraduate BA program and an MBA program. If you look at the core classes the BA and MBA programs at a given university are pretty much the same. Its only on the elective that they differ, and the difference is largely in entry level first job out of college stuff. The work experience an MBA candidate brings with them essentially balances out those six additional classes.
An undergraudate BA program and an MBA program at the same university are not that different.
I've accomplished QUITE A LOT for someone MINUS a masters or PhD
Yes, work experience is quite valuable. That is why the MBA programs don't offer entry level classes as an undergraduate program would.
in the art & science of computing (one of my biggest regrets? Not having gone on for masters OR PhD level in CS actually
Been there done that. Its a lot of fun, going into some old topics much deeper. Having some electives that were not appropriate for undergrad levels. However the payoff is a bit diminished if you do not then work in the field where you did your research. It still valuable, and lots of fun on a personal level, but a bit harder to justify if you will work outside of your research topic.
