Obviously, a world states Cosmopolitanism system could have many benefits. Should be a much more rational system. Reasons are: 1. Permanent armies are not required. Just like Switzerland. Therefore saving a lot of money spending on military set-up, and perpetual peace then could be realised. 2. People would always like to live with like-minded people, Just a human nature. Therefore, conservatives, who prefer to keep living their existing lifestyle/laws without any interference of changes, can simply live with other conservatives, without further frequent complaints anymore about the proposed impacts by progressives. 3. Progressives could have their progressive laws and lifestyle (abortion/LGBT/legal drug/etc), without forcing the progressives for having to follow the upcoming changes. 4. All world states would have small-size governments. A big saving. And much more efficient operations. Any conflicts historically due to the 3. & 4. above would be non-existent anymore. 5. The politicians and state policies would be very much transparent and fairer to their citizens. Instead of sometimes, a federation government/leader/cabinet, once elected, would use the money/tax collected from one state to subsidize another state that they prefer. A human nature. Because they know what would happen after the opposition party after winning next election would do in the future. Many policies (like spending on private/public schools or hospitals, investing in mass transit system or road system, higher or lower tax rates, etc.) are mostly designed and finally made just for ensuring the future winning of their own party. Too much of politics, wasting time/money/energy. 5. Historical conflicts for race, class, faith, ideology, border, illegal migrant, etc could be kept to minimum. Their still will be state borders for individual states, but nobody would want to move/live illegally in a conservative world state that does not like immigrants. Because they when facing problems like famine/war/tyrant/endemic disease/etc can move/live to a progressive state that accept immigrants. Most often they could return to their native states after recovery for helping re-building. 6. A world state is not isolated, because many like minded states around the globe would form alliances and use their non-permanent armies for supporting/defending their civil rights. When any world state acts too aggressively, even some members of its own alliance would calm it down in a more peaceful approach without force. 7. Being a leader to manage a number of states that belong to diverse ideologies, races, ethnics, cultures, religions, etc would be a nature impossibility, and sometimes a disaster. Our human history can prove it already for too many times. A world states for Cosmopolitanism system could avoid and even eliminate this kind of natural catastrophes. 8. ... ...
https://en.wikipedia.org/wiki/Wormhole When the collective monies from all nations, currently spending on armies and arms against each other, can be used for advancement of science and technology, wormhole bridge then might can be fully developed just before next approaching comets hitting our earth! Perhaps! An asteroid and potentially a comet are hurtling towards Earth The comet ”has a good chance of becoming visible through a good pair of binoculars" There are Millions of Asteroids in the solar system, usually found in the Asteroid belt between Mars and Jupiter, however those in that pass the Earth are called Near-Earth objects
https://elitetrader.com/et/threads/...work-restoring-us-manufacturing.307116/page-2 One feature of this world states Cosmopolitanism system is that two neighbourning states can have very different state-wide minimum wages. The states with much lower minimum wages can provide much more attractive labours for labour intensive industries, mainly manufacturing products and processing farming produce. Also seasonal supply of low cost and hence low overhead labour forces can be provided for other states which offer higher minimum wages. Residence rights, which would be mainly for state medical treatments and state education/schools, may not be granted to residences of other states. Seasonal contracting labour from neighbouring states can be sent/transferred back to their native states for medical treatments. Without employing/deploying this world states Cosmopolitanism system, basically the existing developed countries, currently bearing relatively much higher minimum wages would no longer have a healthy manufacturing industry again for their next generations. Their future economies would be getting worse and worse year after year. A big impact negatively to the economy of the whole world in long term!
Trump should be able to make a (say) 10-year trial of introducing a state-wide lower wages for several selective states, in order to rebuild the manufacturing industry in the USA. Other than processing of farming produce, tourism industry should be also benefited by a differential state-wide minimum wages system. Trump is just like Reagan, both are originally and actually Democrats, playing the roles as Republicans to run/change the country in such a way that neither the Republic party alone nor the Democrat party by itself can carry out the transformation policies the US need. Trump saw this was the clear way developing/coming. A conservative party like Republic by itself would not want making changes implemented by a progressive party, by blocking them fiercely. However, only leaders like Reagan and Trump, the Democrats while playing as Republicans, would be allowed for implementing major transformation policies. Even some progressive policies that are fundamentally/traditionally of Democratic principle/nature, like tariffs, anti-free-trade, etc. Therefore, Trump knew that he will be elected for sure. And American now can be possibly made great again! Only when the Republicans introducing some major Democratic-by-nature policies, possibly some similar policies that Sanders once offered/promoted, by not blocking them as if Sanders were the elected Democrat President!
