Switzerland was considered a poor country in the 19th century, but didn't get bombed to rubble in either 1914-1918 or 1936-1945, and so now it's considered rich

Switzerland was considered a poor country in the 19th century, but didn't get bombed to rubble in either 1914-1918 or 1936-1945, and so now it's considered rich. I wonder how solarpunk continental europe might've been now if it had somehow avoided the "short 20th century (1914-1991)".
