I am sure that living from $70/month would be hard for any of us, but some people have to keep their whole family alive from that money, and definately depend on the government this winter. If they freeze, nobody will know about them and they will be just deleted from the statistics.
Heres a video of how the poorest part of Hungary looked like a few years ago, and I am sure their life has just gotten much worse since a few years ago: https://youtu.be/FvoTaqutfVk
I am from Eastern Europe (Latvia) and this does mostly hold true for the countryside: wood burning stoves are common.
However, it is likely that inflation and other cost increases will also affect the prices of firewood from here on out, as well as getting it delivered (unless you decided to secure your own, though depending on where/how you do that, the legality might be dubious).
From what I know of, most people are noticeably hit by the increase of prices in the stores (as well as a somewhat decreased selection of what's available), in addition to greatly increased electricity prices, which has been a topic that gets brought up often in the news.
There aren't that many great solutions for that, to be honest - both diesel generators and solar panels are too expensive for most people, even though there are programs to aid families with purchasing and setting up their own, if they're capable of partaking in those: https://www.altum.lv/en/services/individuals/energy-efficien... (the Latvian translation has more information https://www-altum-lv.translate.goog/pakalpojumi/iedzivotajie...)
That said, it's probably difficult to undertake something like that, when you're living from paycheck to paycheck.
In Eastern Europe, not so much.
edit: I'm glad that you mention Eastern Europe, which is where I come from. Paradoxically, more people die from cold in the West, because their milder climates don't force them to invest in insulation.

Should've bought local, but as someone from a poor country neighbouring the EU - fuck that, learn to make quality or you deserve to go under. I'm not paying 2.5x the price for local atrocious quality.
And farmers saying lack of rain will ruin them can Google "artificial irrigation" on their gigabit fiber and unlimited 4G. But hey, I guess those new BMWs were worth it.
Not just energy, but food, vaccines, medical supplies, consumer products, etc. This has always been the case but now it's at the point where third world countries will probably have major civil unrest and emigration due to the shortages of food and energy they will face from being outbid by Europe and other rich countries during this shortage.
Europeans can resort to going on fewer and less expensive vacations to compensate for the increased prices of energy, food, game consoles and GPUs, but I doubt anyone here will actually starve or freeze to death, while that may be an actual reality for some people in some developing nations.
