Racism and all forms of intolerance are having a renaissance in the US. Whites are shrinking as a percentage of the total population and that really frightens and angers some whites. Politician like Trump can exploit this anger and fear, even though they can't change the population trend.
As I understand it, just about every 'white' Western country has a growing white-only, white-supremacy, neo-nazi movement. It's hard to imagine something like that in Sweden, but I know it's happening in Canada, and they are the Sweden of the New World.
Global climate change and wars for control of nations around the world will greatly increase the problem of refugees for al the 'rich' countries. NO country will be able to open its borders or adopt a more liberal refugee policy. This is a problem that will grow worse and worse in decades to come!
