Japan especially is likely going to have severe issues in the coming decades. They have an aging population and thanks to a deep seated sense of nationalism, they don't really embrace immigrants.
I think this is one of the more important facts that gets ignored in all of our political debates. Birth rates in first world nations has really declined since the 60's, and this has put a real stress on social safety nets as the Baby Boomers hit retirement age. Young immigrants and their children are a boon for any first world country.
