What was the attitude of ordinary Germans towards the Jews before, during and after Kristallnacht?

Kristallnacht seems to be an inflection point in the persecution of Jews by Nazis. Before Kristallnacht the Nazified state institutions were openly anti-Semitic but the ordinary population while prejudiced against the Jews, saw them as a fixture of everyday life. The Kristallnacht pogrom seems to have been a catalyst for ordinary Germans to go from mere anti-Semitic prejudice to active, enthusiastic persecution. And in many cases, profiteering from that persecution. I am looking for accounts of this from ordinary Germans and not just from party officials. What made middle class Germans, who before 1938 had not been hostile to Jews, change their attitudes so drastically between 1938-1942?
