My understanding from watching Top Gear is that old cars–in running condition but without many miles left on them–are cheaper in the EU than in the US. Something to do with the EU’s end-of-life vehicle recycling mandate means that the scrap value of the vehicle when it ultimately dies is less in Europe.
Objectively, Americans spend a smaller percentage of their income on food than anybody else in the world, yet manage to ingest more calories than most. cite, cite.
Comparing food across regions is a funny thing. I have relatives living in various parts of the U.S. When the come to visit me they always complain about how expensive groceries are here. When I go to visit them I always complain about how expensive groceries are there. I think I have figured out how that is possible.
When you live in an area more than a few months you get a good idea of which stores are the cheapest sources of which foods, how long you have to wait for a good sale, how much to stock up when there is a good sale, which foods are always expensive and which cheaper ones make good substitutes. When you do your shopping in an unfamiliar area that you’re only visiting, it doesn’t pay to do a lot of research. You just go to whichever store is most conveniently located and buy what you want when you want it. You end up paying more than a reasonably frugal local would.
The problem is compounded if you’re in a foreign country. If you insist on buying the same sorts of foods you do at home rather than what the locals eat, you’ll pay extra. If I, as an American visiting Europe, insisted on eating grits, Lucky Charms cereal, and peanut butter I would have to pay dearly. If I could even find them, they would likely be imported all the way from the US. Also, recent changes in exchange rates (e.g., the post-Brexit collapse of the pound sterling) have to be considered.
