I have an MBA from a mid-tier school. Top 50 but not top 12. I don't really have any regrets other than I initially started at a third-rate school and decided to transfer after two semesters. The differences between the materials were negligible. The differences between professors was noticeable but not alarming. The differences between classmates was the part that was alarming. From talking with MBAs from top programs, I know their material wasn't substantially different either. So the value isn't entirely the material. It's functionally working with and learning from other smart and driven people. Class discussions are better, class projects are better, and you learn a lot watching others do the same work as you in different ways.
My post-MBA job probably could have been gotten without an MBA. There could have been other things I did over those three years of evening classes to improve specific skills. However, having the MBA on my resume expands the types of companies that would hire me for senior management positions. A lot of job postings in my area are still MBA-preferred. It may not be like that in younger companies or higher-growth cities, so I understand why this type of content ends on on HN frequently.
