Just to play devil's advocate, I'm not sure your answer to number 2 is relevant. Sure, the US probably has the best ecosystem for starting a country, but why would that lead to the idea that the US should let anyone who wants come here to use it? Norway has a great health care system, but that doesn't mean that they should allow anyone to emigrate there who is looking for good medical coverage. Also, for number 1, I dont think thats a fair comparison. If anything, the recent startup culture in the US has proved that theres an enormous ability here for citizens to start their own companies and fight against large, slow moving corporations. Additionally, there is no shortage of US citizens trying to start companies, who are well aware of the advantages. It seems like your plea is more from the idea of "its not fair that the US is the best place for this, so they should allow everyone to try it", which just is not how US immigration policy works.
