Some of the nostalgia for A-H empire is driven by the hindsight of "what happened after 1914". Which tends to give you rosy glasses.
The Austrian part (Cisleithania) was okayish place to live, relatively industrially developed (less than Prussia or England), but it had a massive problem with political dysfunction. The Babel of nations was unable to agree on pretty basic things, resulting in paralysis of local and central parliaments and frequent governmental crises. There also was visible, very nasty anti-Semitic resentment. Hitler learnt to hate the Jews from certain Georg Schönerer [0], a rabid Austrian Jew-hater who came up with the idea of a "Final Solution".
The Hungarian part was outright backward and oppressive towards non-Hungarians, who constituted at least half of its population.
I was curious to learn more about that claim about Hitler's origins, because Hitler himself explained how he became an anti-semite and I don't remember Schönerer appearing anywhere in that explanation. But the wiki link doesn't explain either. It just makes the same claim and cites a book from 2017. It turns out that book is readable on Google Books and it also doesn't provide any evidence for the claim of a Hitler/Schönerer link. It just asserts it without presenting any evidence or any further citations, in fact, the entirety of the argument is that Hitler was "no doubt" influenced by Schönerer. This is a worse level of evidence than a tweet.
Also you claimed Schönerer is the origin of the Final Solution but the Wikipedia page doesn't say that, so where did that come from?
I honestly wonder if Wikipedia should cite books. It's too hard to check those references so people don't and that lets un-evidenced claims get treated as "reliably sourced". Putting something in a book doesn't magically make it more reliable than putting something in a blog, yet Wikipedia's policy strongly assumes that it does.
