Why? The rent doubled, the buses were full, taxes increased and crime sky-rocketed as immigrants who didn't have enough to eat crowded on to Sweden's generous social benefits scheme. The swedes, with a proud tradition of construction unions, heritage planning and social consensus didn't have the ability to reach an agreement on how to feed and house so many immigrants so quickly. This led to the migrants literally building a shanty town around the Malmo benefits office, instead of being allowed to build homes for themselves, as the EU refused to support the lone member state that did the right thing.
Proportionally, this influx would be like 5 million people arriving and applying for asylum in the US in a single year. [1]
As I witnessed these kind and tolerant people transform into the racist bigots this lady encountered, I think things would have very been different if the planet had treated the 2015 refugee crisis as a common problem, and not dumped it all on Sweden.
No, there is no excuse for racism, or for the lack of action in this case. But there are forces that provoke it, and every country that didn't take in a proportionate number of refugees during this crisis shares the blame for the social mess that Sweden is in today.
