Why do people repeat this canard? I saw it on HN yesterday. Meanwhile, after ignoring very small countries, countries like Australia and Switzerland have twice the percentage (about 30%) of immigrant residents than the USA, (about 15% — even Germany has more). The US is a large country so the absolute number is higher than, say, Switzerland, but not by orders of magnitude.
