there is also another question. the figure you cited for Germany is gross wage. net wage would be €3,324/month, or $45,536/year. is "income", in the US survey, after taxes? i wasn't able to find the definition of "income" in the American Community Survey, but i notice that besides "income", they also have "earnings" (which is higher).
finally, we need to correct for cost of living. i think that would explain a lot of the difference.
the average household income for Mississipi is given as $76,305/year by this US census link: https://data.census.gov/table/ACSST1Y2023.S1901?q=S1901&g=01... (which is cited in the Wikipedia page you cite)
