The Latin thing is only a partial explanation. Some of it is changes in pronunciation coupled with a very authoritarian attitude to orthography. Few languages out there that changed so little in 400 years.
So for instance the -ent ending for plural verbs (“ils mangent”) is silent because the “ent” sounds were progressively dropped. Then the written suffix logically started disappearing, and only then did the Académie bring it back because it was more Latin. If it wasn’t for these reactionary fucks that rule would have been reformed centuries ago.
Unfortunately in the intervening time, knowledge of orthography became a very strong social marker. Because spelling French is so hard, the dictée came to disproportionately affect grades (seriously, old-fashioned schools still do it daily and it’s all graded and very severely), which coupled with the industrial revolution and alphabetization of the lower classes meant that shit spelling = prole = bad. So now orthography is at the center of the traditional value system which has all the conservatives pearl-clutching at the idea that children can’t spell “nénuphar” properly. Children’s purported inability to spell properly is like the number one moral panic that has sprung up every few years for the last century or two, but also orthographic reforms are woke (derogatory). The point of orthography, to conservative types, is for it to be hard so you can show off your perfect spelling to justify your social standing.
Belgium has some of (if not the) lowest income inequality in the OECD due to our very harsh income tax (highest median tax wedge of the OECD, yes even including the nordics). With quite a few asterisks attached to that statement of course because our fiscal system is a complete mess so if you’re special kinds of well off (e.g. you make your income on capital gains) you’ll be taxed very little.
How low income inequality doesn’t correlate to very high standards of living like it does in the Nordics… Well I’ll leave it to historians and economists to hash it out. The answer you get will almost certainly reflect that person’s personal politics. Harsh industrial decline is worth mentioning though.
Wallonia is measurably poorer than Flanders, but both regions are developed western economies. The US has a murder rate 535 % of Belgium’s, and I don’t see anyone warning students away from studying there (or well, not until the past few months).
That judge should be investigated and the prosecutor should definitely appeal, and besides there is a lot of work to do safety-wise, especially for women to be able to feel safe, but that’s hardly a problem specific to Leuven or Belgium.
