The worst case Euro disaster might be in Finland. Compared to Scandinavian economies with their own currencies, the real inflation has been horrible.
1999 one could buy a carton of milk for 1mk, exchange rate to Euro became 6:1, now a liter of milk costs about 1,2€. So the actual purchasing power has decreased close to 20% a year.
Same has happened to Spain, for example. Many services are bankrupted, so it is hard to imagine ever returning to the time before the Great Reset.
Marks were before my time here, but in the first few years, a lot of people I know were still calculating prices in it. A lot of small prices got inflated very fast from what I hear. However, there have also been some benefits for Finland too I assume.
I think the biggest issue here at the moment is wage stagnation and people increasing their personal debt to maintain lifestyle.
The monetary system itself is the big problem mathematically, but physically they have pretty much ended decentralized food production. Services are bombarded with regulations leaving only multinational corporations left.
Was born close to the Arctic Circle, witnessed small farms being shut down and services escaping elsewhere. If the resources do not exist, the paycheck is the least of worries. Also the government taxes even the neighbor help, so they made living inside the system almost impossible.
I have heard of many people who are claiming EU rebates on farming land that they don't use and the like. There is a lot of weirdness going on with it, but overall - no wars likely. With a different kind of economy in place, one that doesn't rely on borders and nations in the same way, this is possible without the centralization.
The EU has skipped paying farmers their benefits many times, so there are no more small farms left. Also the requirements and directives are so twisted, that family farms are required to be companies, which makes food production centralized.
Also Finland has no trade borders, the products going in an out are controlled and taxed by the EU. Russia used to be the main trade partner, but now it has pretty much halted.
Being part of the United States of Europe has very few benefits, but many problems. There are no more Government-owned companies or infrastructure left, privatization has taken over. Surprisingly, there are still many small businesses and farms functioning in Spain.
Why? What is the difference?
I suppose majority is cultural difference. Finnish people are usually pretty quiet and reserved, while Spanish people have close family and friend connections, also with the community.
Also people are less authority-obedient down south. The government has not helped the people before, so promises are not taken seriously. Banning singing and dancing in the streets got rid of most of the culture, hopefully it will return someday.
Surely the farming is way easier with warmer weather conditions, in Finland you get one harvest a year. So the food will not be the problem in Spain, in Finland it might become pretty scarce.
So also the paycheck does not matter, if there is nothing to buy. Tiny economy like Finland seems to get the short end of the stick.
