> America is the richest country in the world.

In absolute terms, yes. But per capita there are quite a few richer countries, like Switzerland, where people genuinely seem to brave the elements as part of their culture.

Sure, everyone adopts conveniences, but I've never seen anyone do it to the extent Americans do.

The per capita numbers are more recent as opposed to be throughout the 20th century but even still the size of the Swiss market (in absolute terms) is tiny compared to the size of the American market. Unless the per-capita wealth or disposable income is 30x to make for the population size difference, the "reducing discomfort" goods market will still favor the larger (overall) richer and bigger markets then trickle down to smaller ones. I highly doubt the Swiss endure through cold winters by wearing more layers in doors and drinking lots of hot tea.

Sounds more like observational or cognitive bias tbh. For example, the Japanese market is notorious for building gizmos and machines for far less grand inconveniences that the weather or long-distance travel. They eat a lot of rice in Japan, so it makes sense they invented the rice cooker. To many Americans (today) who don't eat a lot of rice having an entire appliance for just cooking rice might seem like a crazy war on discomfort and too much of adopting convivences. What's next? a machine just for Turkish coffee?
