From your link: "equivalised disposable income"

So it sounds like this isn't gross income.

Here is the explaination.

"It is measured by the median equivalised disposable income, after adjustment for differences in price levels between countries. This means that despite the high price levels in Switzerland, the population's financial situation, after deduction of obligatory expenditure, was in 2020 more comfortable than that of its neighbouring countries and countries in the European Union."

So the disposable median in Switzerland is about the same as the gross median in the US. It looks like the equivalised disposable income for the US is not calculated, so we can't compare that. Having a median disposable income that is about the same as the gross median of another country still seems to support my implication that the Swiss are more wealthy and can better afford the cost of gas as compared to the US.

It seems it's hard to get "good" sources for Swiss median income. They do list the median monthly wage as being around 6500. This doesn't include other income sources, and is still about double the US median income.
