He is in a position of huge influence in the new government, which I think some people underrate. A great admirer of Bismarck, I very much doubt he cares much for the policy opinions of the people he pandered to to get power.
Morally, the British people owe the people of Hong Kong citizenship. Economically, it makes a great deal of sense, especially as those who move will most likely be younger people.
It will be interesting to see what he does. Though no Bizmark, he has a sort of hacker mindset to politics that is unusual in this day and age.
From an outsiders perspective, I like free trade and free movement of people, but I hate stultifying bureaucracy.
Or to put it another way: I like it when governments compete for citizens and capital. I dislike it when they have the capacity to coordinate against same.
So I consider the EU as something of a mixed bag.
Problem is you can make that same moral argument for all of India, Pakistan, Bangladesh, etc.
Idunno man, I don't think hardly anyone would have a problem with tens or hundreds of thousands of largely civilized, decent, educated people entering Britain; provided it was not in addition to what they're used to from other places. At least, this is what I gather from speaking a lot with Brexiters and marginal remainers.
It feels like the seventies or eighties again in terms of the stupid, and inconsistent attitudes. Some people think it's OK to be visibly racist again.
