The US has a far better track record than any other leading power in history when it comes to facilitating the development of other countries into nice places. See e.g. http://davidbrin.blogspot.com/2009/11/how-americans-spent-th... , or consider the motivation behind the Optional Practical Training student visa provision. As a US citizen, I personally spent three years working in China for a Chinese company, on salaries in line with those of local PhD staff, and nobody lifted a finger to stop me from developing cutting-edge technology for them; this may be slightly more restricted today in the specific case of China, but a younger analogue of me interested in applying what they learned from US grad school to problems in India/Indonesia/etc. faces few barriers from the US side, beyond unusual income tax and other financial considerations that only really kick in if you're already making enough to live like a king.
Yes, I want nice things. And I want as many other people as possible to have them as well, which is why I'll remain opposed to US-weakening policies until we have a #2 power that's even better at helping foreigners than the US.
You can be opposed, but that doesn't make your position correct. In fact, based on your steadfast commitment to your position despite the glaring evidence I've put directly in front of you, that... kind of makes you stubbornly closed minded.
The fact that you're not even talking about the things I mentioned in my earlier comments should be a red flag for you; why won't you talk about the facts related to immigration into the US? I wonder, maybe it's because the facts won't support your position?
1. How relevant is open space when a majority of prospective low-skilled immigrants want to live in already-heavily-populated areas, not North Dakota?
2. I already mentioned that the other countries most comparable to the US (Canada and Australia), including on the open space dimension, make the same hard distinction between high-skill and low-skill immigrants... and they are doing conspicuously better than other Western democracies at simultaneously maintaining high immigration volume and avoiding populist revolt. It is not my problem that you failed to parse this. New Zealand did see a political turn in favor of more restriction recently, but it was from the left. If anything, it's Singapore's lack of space that makes it practical for the Singaporean government to enforce the conditions under which they can keep so many guest workers around to mutual benefit, such as no pregnancies.
Yes, I want nice things. And I want as many other people as possible to have them as well, which is why I'll remain opposed to US-weakening policies until we have a #2 power that's even better at helping foreigners than the US.
