I've never encountered the depth of discussions we have here on other SF boards (Star Wars, BSG, Star Trek, Battletech).
Battletech boards definitely has it. BT science and economics especially is totally out of whack and has given rise to ridiculous amounts of discussions through the years.

I'm not certain, but given all the taxes on the wealthy, the BLS may be the actual earned wage was well as the minimum (The workforce may be taxed so that the remains of their pay is close to the BLS.) In such a case, there is no incentive to work, or to work better, beyond self - recognition. Given that, education is meaningless - an academic could choose at any time to live on the Dole and live a care-free life, reading and studying with no pressure to produce or succeed, and still get the same wage and living conditions.
From what is mentioned in the books, it doesn´t sound quite that extreme. Probably not much of a difference at the LOW end of jobs though.
OTOH, at the same time, if you provide ok living for people and leave them at that, then a normal response after the first few months tend to be that a large part of the the group will grow restless and start looking for something to do, or come up with it on their own.
So, even with botched education and economics etc, a lot of people would still educate themselves or "amuse" themselves by doing things that are effectively "good for the economy" indirectly(or potentially even directly if they´re crafty enough to start a business regardless of problems).
Essentially, the Malign almost certainly didn´t just muck the place up, they probably maintained enough influence to make sure it STAYED screwed up.
Then the revolutions killed off most of their influence, and suddenly Haven can fairly quickly manage to get back on its feet.
Haven is simply too big and diverse to so quickly go keel up in so many ways if there isn´t an outside power affecting it.
Rules and regulations have to be so outright bad that they stymie any local or even planetary attempts at improvements AND even manage to kill off any functional economy that is conquered.
Education has to completely bolloxed and kept that way.
Chances for individuals to get access to facts and education literature has to be removed to keep people from taking their own initiatives.
And so on... Keeping it down so totally even in a small country isn´t entirely easy, and in a many-planet, many-billion population, it will probably be hard to keep it that way.
So my conclusion is that the Malign actively interfered to mess things up all that time up to those revolutions, where their people got trashed.
