Protests, demos and tumults are almost unknown in Singapore. But recently people there staged a demo. Their discontent was against immigration.
Turns out that in many countries immigration is not exactly popular. The opinon polling firm Ipsos has surveyed a range of countries. This is from their Global Advisor site:
In none of these countries does a majority think there are too few immigrants. Poland comes closest with a plurality of 41% saying it has too few.
There are plenty of countries in which a majority thinks there is too much immigration, including such non-Western places as Turkey, Saudi Arabia, India, and South Africa.
Why South Korea and Japan have such large contingents of “don’t knows” I myself do not know. Perhaps the issue is much less salient there.
