Working for company X and having a substantial portion of your retirement plan in company X is simply exposing yourself to too much risk, because the company is both your employer and the source of your retirement income. So if something goes wrong, you lose both your job and your retirement plan.
The math you need for most of finance is ninth-grade algebra, and most people feel reasonably comfortable with that. But I think the financial world there has been - I don't know if it's by design, or this is how it's evolved - there are bad actors who have wanted to obfuscate because you can benefit from the lack of transparency.
