The early Zionists changed their names, changed their pronunciation, purposely killed Yiddish, and tried to establish Israel is an un-Western culture in a lot of ways; ever notice how most of the restaurants in Israel are serving Middle Eastern food when the country was founded by Europeans? The myth of Ashkenazi elitism among the early Zionists needs to stop. They didn’t just hate traditional Sphardi culture, they hated their own culture too. Just like all socialists, self loathers.
As to the OP’s question, America is like 95% Ashkenaz, so it’s not really a fair comparison.
