Oracle is mediocre because it could be.

That's probably where you'll end up if you're a company where that's an option.

No one was ever going to switch databases to a better DB as long as:

1) they did the bare minimum to ensure no alternative existed where switching made any sense.

2) they never charged too much where it made sense to switch thinking along the lines these businesses made decisions.

It's like the resource curse played out on a company scale.

If you have no incentive to get better, you won't.
