The US does have different enlightenment-era founding principles from countries that are based on ethnicity, religion, or even a shared history according to its founding documents. The priority for individual dignities may conflict with ideas about social safety nets that have become the norm, but it is compatible with sympathy for people who are oppressed and who are undermined. While immigration is critical to the vitality of the US economy, that is not its only goal. Furthermore, an attempt to optimize immigration for the predicted economic output of immigrants won't necessarily have the most favorable economic outcome. I think Silicon Valley itself serves as a perfect example. There is a significant number of second generation immigrants whose parents escaped abuse somewhere else in the world, then worked hard at a menial job to raise children that went on to do something great. Whether or not there are problems with the interview processes, making the world a better place by getting people and their families out of terrible situations is a good goal on its own merits. There are a lot of loud anti-immigration people in the US who claim to be proud of selfishness and potentially undermining the economy, but the actual experience for immigrants is better than elsewhere according to friends who have worked around the world.
