Yeah, I bet none of that 72% ever stood in line at the bakery, merely hoping there was still some bread left when they got to their turn. Or having to help offload PB gas bottles from the train, because otherwise it was almost guaranteed there wouldn't be gas to cook with.
As for the poll, there's a lot of complex social reasons behind it. But what I consider the most important is that we have the newest brand of authoritian government in power for the majority of the last 24 years with completely unchecked power, and the only things they are good at is corruption and brainwashing the voting populus. The last decade has been an unmitigated failure for Hungary, and despite that, it's still ahead of the communist system I grew up in. We are quickly moving back to the same authoritarian system, though.
Edit: and since our current system is very intent on replicating the mistakes of the ole' communist system in exactly the same manner, we are very much on track to implode again in the same way. Yay for us.
Oh I hate the current system. Just marginally less so than the previous one, mostly due how the current system worked around the 2000s. The current debt spiral is not a coincidence, it's the same effect in play as it was with communist era. Orbán is building up the same system we had with Kádár or even Rákosi - a bunch of state-owned or state-controlled companies organised by a central planning committe which may or may have accurate ideas of how the economy should work
When the hungarian communist saga began, there were a few incredibly stupid ideas they implemented, but the example I'd go with is "We will be the country of iron and steel" (a vas és acél országa leszünk). It was more or less forcing heavy industry on Hungary, despite Hungary having basically no reasources or reasonable ability for anything such. But, since that was what the communist party decreed, it was carried through. Make a bunch of such decisions with impunity and you have a lot of flaws in the economy, each making it do worse. It's how a dominantly agricultural country managed to have a famine, too... which lead to a revolt and the downfall of Rákosi.
Then when Kádár replaced Rákosi, and things improved but nothing fundamentally change. We were still part of the USSR - he was kept in power by the Red Army - so there was no way to admit the communist model he inherited was failing. So they kept it chugging along, financing the crappy economy from increasing debts. Until the whole thing imploded.
And now we get to modern Hungary. Orbán is in power. He has hsf complete free reign of the country for what, 14 years? Our biggest domestic produce is now propaganda, which is probably the only thing that works properly now. He is changing every law any day as he sees fit. He's turning most of the economy into state-owned or state-controlled companies. He can even decree how the economy should work - since they can pass any laws, he can freely control say, the price of anything (they just did enacted a new such law today). He even decreed we'll be the country of batteries, and decided that hungary will be sporting a few dozen chinese battery factories despite us having no resources or any geographical/societal potential for such (we'll be importing all resources for the factories and we need to use chinese/phillipine labor there). And to make this crappy economy chug along, we're getting increasing amounts of debts to mask the inefficiencies. Which, I think, will soon implode on us.
As for your question, I'm not sure if it's communism or cronyism that was the issue. A country is a big and complex thing, and it's hard give hard answers, Did the Rákosi/Kádár system fail because they pushed commuism too hard, or was it because they were idiots following the wrong idea? Probably a bit of both if you ask me. The way they implemented a planned economy was a top-heavy system completely impervious to criticism. And for most of us that was the communist system playing out in reality.
There could've been cronyism involved, but probably wasn't much. If anything, our current Orbán system is displaying cronyism and corruption way worse than the previous ones. Funnily enough it's driving the nostaliga for the old system back, but it's also not counteracting the propaganda to make people not keep voting this shit back every 4 years.
