I haven't caught up with the rest of the thread yet but I just wanted to return to Popper and Soros. Popper's paradox of tolerance is the well-known relativism argument, which, philosophically, there's little or no answer to. Relativism moves societies to an impasse because of political, conceptual or ideological paralysis (the inability to take a position) and infinite regress (the 'whataboutery' nature of arguments). Popper talked about protecting your own values (he was referring to 'our' liberal values) to try to go beyond the whataboutery and political paralysis of relativism (infinite tolerance). I actually don't mind Soro's Open Borders if, as according to the mission statement, they aim to spread European liberal values elsewhere. What I do have a problem with is that the mechanism that has been adopted in order to achieve this is clearly bonkers. This makes me think that there's obviously some political goal behind all of this because any layperson can see that 'spreading liberal values' by migrating peoples with illiberal attitudes to the origin of these values, rather than spreading these values outwards, is crazy. Whether it's for the benefit of the Global Governance-type of rule, I don't know.
Inequality of also hard to live with. There's a lot of evidence (the book 'The Spirit level') that extreme inequality creates problems in societies for everybody - even the rich. Eleven measures were used such as crime and incarceration rates, mental health, obesity, educational attainment, etc.. People at the top are also affected by crime, etc. as they can't hide themselves away consistently. Also, on an individual level, it's hard for people to live with extreme inequality (e.g., slavery) in terms of their own feelings and emotions, so ordinary people fare better in more equal societies. But, as societies equalise, we are then back to the paradox of tolerance, freedom, equality, whatever you want to call it.
So, what we are seeing could be a theoretical move, to try and rid societies of the constant cycle of relativism (communism)/inequality (capitalism) by the Bilderberg group of rich people, academics, theoreticians, etc.. Whatever is happening, I doubt very much that it has been accidental or circumstantial. The migration that we are seeing has also been from predominantly Islamic nations - why? We don't have any answers to this question either. There are precedents for bribery, deal-making and mutual back-slapping.
So - no answers from me, either.
