I'm not quite comfortable with the implication that surviving the Holocaust is something one should feel quilty about.
even if you aided the Nazis?
a) Soros was 14 at the time.
b) He didn't actively hurt anyone as far as I can gather from that interview. Just participated in the confiscation of goods that were going to be confiscated anyway.
c) How many came out of the Death Camps as morally pure as they had entered them? As Primo Levi explores at length in his works, part of the KZ's perversion was that they forced you to be a wolf to your fellow man if you were interested in in survival. 'Survivor Guilt' is a well-documented phenomenon
d) As a general rule it's best to abstain from judging the survival strategies of people during the Shoah if you have never been persecuted yourself.*
*: There are obvious exceptions to that rule, but Soros isn't one of them.
Disclaimer: I actually personally dislike George Soros at least somewhat.
