Investors, early stage in particular, are optimizing for exits, not profitability. I know that's not what's on their mind when they're advising (I assume the best of intentions), and they do provide the best of what they have, but if that's what gets rewarded, that's what'll get optimized for, and there's nothing the "Good ones" can do about it if they want to be/remain successful.

Very few people other than those pesky customers, seem to care if a business is actually making money on its own these days.
