As much as I disagree with Trump on almost everything else, he's not wrong to classify such countries in this way.
I mean, what are countries like Nigeria, Congo or Pakistan - other than sh*tholes ?
The Austrian school of thought on this subject doesn't have a great track record, thx
That's not true. As one of the most affected countries by the recent immigrant wave, now-Chancellor Kurz was responsible for closing the Balkans-route.
Otherwise, there would be even more terrorists and welfare abusers (posing as refugees) here right now, endangering European countries.
So, please think again when disqualifying the "Austrian school of thought". Besides, it is not an "Austrian school of thought", it's called common sense.
