I don't understand why America, long a champion of immigration, doesn't open the floodgates back up.<p>We could onshore factories and staff them from all over the world. Pay workers wages comparable to what they would get from working in factories at home (ie. not "US wages" since we can't compete on cost with China, Vietnam, etc.), but give them decent hours, a housing stipend, education for their kids, and a promise of US citizenship. Also offer them courses on American culture, English, etc. "Melting pot" rather than unsupported labor. We could make it really comfortable and attractive.<p>To incentivize business, we could offer zero taxes over the next fifty years to run factories domestically. Start with the critical pieces, and then build everything.<p>Growing beyond 300M would also dramatically increase our consumer base.<p>To keep natural born citizens from getting angry, we can offer tax incentives for people having children. We can pay kids $20/week to study and get good grades (not a bad idea - it especially incentivizes poorer kids!). We can also grant credits for kids that excel in math/science, music/art, sports/club, etc. Keep them engaged and growing.
