In reply to Big Ger:
It continues and it's probably here to stay... The current situation of wealth inequality (both between nations and within nations) is probably unsustainable. The internet shows an increasing number of less fortunate people what they "could have" somewhere else...
Add to that the pressure on food resources that is likely to arise from climate change and global population growth and it's easy to see how the desire will likely remain in many people to move to a place where they think they will have more/better opportunities.
And that's not even mentioning the useless class that could be created by artificial intelligence/automation. It is likely that, even in developed countries, that the wealth gap will grow. As more and more people have access to internet, advertising etc, they see how much more comfortable life appears to be elsewhere. We already have a huge number of people globally who, purely because of the piece of land on which they are born, will likely struggle to escape poverty and/or be persecuted for whatever reason. At the same time, there could be an increasing number of people in the UK and similar countries who can't find employment and struggle to make ends meet. Politicians and the media will likely stoke up further feelings of fear (they're taking our jobs and our school places, healthcare services etc etc) to make sure a majority don't think it's in their interests to help economic migrants or refugees...
What's probably required is more international collaboration at this stage on trying to find workable solutions and compromises, whatever they may be. Sadly, though, we are at a stage where the average American doesn't want to pay a few more cents in tax to ensure access to healthcare for less fortunate fellow citizens...what's the chance of them giving a damn about poor foreigners? And in some European countries we like to feel we are more powerful than we are, so when others come up with a solution that involves us helping out a little, we spit the dummy because it wasn't our suggestion.
And war...another factor that clearly has impact on making people leave their home countries unwillingly, in search of a safer place.
I think it's a crisis that is going to grow and cause further tensions, unless countries can begin collaborating a little more with the goal of finding innovative solutions.
