Well racism and xenophobia are often products of income inequality. Its what happens when you pair poor education with poor living standards. Your judgement becomes based on emotions that can be easily swayed by a political class ready to point the finger at anyone but themselves. Hitler's opportunity wasn't that germany was racist, but rather the brutal socioeconomic conditions of the weimar republic. One thing though makes way for the other.

The sad thing is that brexit wont do a single thing to diminish austerity. On the contrary its the people who voted out who will be affected the most.
