In fact, it was a far more optimistic time than since about 2020, as soaring cost of food and going out means even privileged middle-class people are complaining, and infrastructure improvements have stagnated.
One of the best books I’ve ever read, extremely enlightening.
I've had pretty good time in "Eastern" (Central) Europe, so did my wife in China.
People were still optimistic about EU/euro, that lasted roughly until Lisbon treaty when they forced Ireland to repeat the referendum until they got result they wanted, which later become EU's MO and since then it went all downhill, with another major successes as Wir schaffen das 2015, Green deal 2020 or Totalitarian COVID pass 2021. Hard to understand someone who can still support this failed project. I would just dissolve it and return back to EEA.
Next time maybe ask actually people from those countries instead of parroting some writer.
