I am posting this based on comments in another thread which I don't want to derail. However, the comments posted suggested that America should be importing more Europeans than those from third-world countries. That actually presupposes that Europeans are lining up to immigrate to America. However, the fact is that America is plagued with a very low birth rate.
"The new birth rate numbers are out, and they're a disaster. There are now only 59.6 births per 1,000 women, the lowest rate ever recorded in the United States. Some of the decrease is due to good news, which is the continuing decline of teen pregnancies, but most of it is due to people getting married later and choosing to have fewer children. And the worst part is, everyone is treating this news with a shrug."

Europe has a very similar problem:
"Europe is ageing. On average, each woman has 1.58 children in the EU, substantially below the 2.1 children needed to sustain the current population level. Due to low death-rates and high net-migration, the overall population in Europe may be increasing, but the median age is crawling slowly upwards: 42 years in 2014 compared to just 29 a decade earlier."

So, if you are tasked with population replacement, do you bring in more people who won't reproduce or do you bring in people who will produce future tax payers.
Discuss.
