Right wing politicians are exploiting the population around the world by blaming migrants/refugees for all their problems.
Engage in discussion people. Downvotes are for quality, not disagreement.
I cannot figure out how to get an answer to this.
How do countries without large immigrant (I won't even go to refugees) populations handle this? Switzerland seems to be doing fine. Japan isn't falling apart because there's nobody to cook. Most of Asia is doing fine without allowing any immigrants.
So on a strict analysis of whether immigrants are beneficial to the host population, your argument isn't made.
2. All the talk about Japan economy doing badly is nonsense. If you believe that narrative (which is totally understandable as that's the conventional wisdom), I strongly suggest you read this article: http://www.nytimes.com/2012/01/08/opinion/sunday/the-true-st...

I guess because the rivalry would have no meaning and no real benefits, and could lead to needless aggression. And because having conflicts with faraway people I'll never meet is bad enough; having conflicts with my neighbors is an unsettling proposition.
How permanent is that solution? If a child born on the opposite side of the street had access to good education, health care, and jobs, could they also become "intelligent, wealthy and altruistic," and if so, wouldn't it be in my best interests to help that happen? Or even for no direct benefit, wouldn't I just want to help because of that altruism you mentioned?
Conversely, if they are kept isolated from us, wouldn't it make it even harder for them to achieve that potential? If so, doesn't their enduring poverty and lack of intelligence and empathy mean that they're more likely to grow up to commit crimes on my side of the street?
