> The "fix" for reducing migration isn't to raise up walls and barriers, but to help improve circumstances in the country of origins
Migrants are typically among the most motivated people in the source country. They are the ones that can get it together to organize transport, travel a great distance, maybe learn a new language… altogether a great effort. Perhaps one way to improve circumstances in the country of origin would be for those people to stay at home and put their effort into their own country.
But it turns out we actually like the economic consequences of having those type of immigrants in our country. They are, by and large, hard working and skilled. And so we continue to brain-drain the countries of origin, at their expense.
That said, it reminds me of the EU paying Libya and Turkey to keep migrants/asylum seekers from crossing over to Europe. I'm not convinced the migrants are being treated fairly.
The "fix" for reducing migration isn't to raise up walls and barriers, but to help improve circumstances in the country of origins; improve stability and economic outlook and the like. That said, another approach to reduce migration to the UK seems to be to make it less attractive.
