Historically, there have always been groups which politicians felt comfortable demonizing. Sometimes they were religious minorities who had been able to amass money - the Jews come to mind and it wasn't only the Germans of Hitler's regime who looted Jews to fill the exchequer (consider the Passover that begins next week).

When the Nazis came for the communists,
I remained silent;
I was not a communist.
When they locked up the social democrats,
I remained silent;
I was not a social democrat.
When they came for the trade unionists,
I did not speak out;
I was not a trade unionist.
When they came for the Jews,
I remained silent;
I wasn't a Jew.
When they came for me,
there was no one left to speak out. - Martin Niemoller
