The vast majority of Jews in Europe have never been rich.
The Jews have been used as money lenders, as rent and tax collectors etc. in various places (from Poland to France), feeding popular antisemitism. Necessary but extremely unpopular social services. They were often expressly forbidden to do almost anything else. So, the Jews got to do the dirty work of kings and nobles and when these couldn't repay their debts, the Jews would more often than not be booted out of the country. Common folk would resent them since often some Jew would turn up to reposess the pig. The pig would ususally end up with some god-fearing christian nobleman.
However, if you look to the first crusade, the ideological content goes well beyond resentment of economic success. "Rich gits" was less a factor than "Christ killers".
