A future one-world government would work very much like any other government of an industrialized nation today. There will be three main pillars that comprise of all the activities and regulations that this new government would come up with; health (welfare), monetarism, and religion. Each will be tied closer together than in the governments of industrialized countries today.
Health and welfare are just those. The new world government would assume responsibility over all aspects of your health. Medicines would be rationed, research and development would be funded by this new government (as there would be no payment for medications from the private sector, at least in the individual’s budget), and a welfare world-wide nanny state would be in its infancy as this new government would begin to come to fruition. You think healthcare will be universalized now? Wait until this new government would socialize the entire industry worldwide. Your health would be directly in their hands. If you eat too many unhealthy foods, your medication rations may get smaller. If growing your own food isn’t a crime, the knowledge on how to do it would be heavily back-pedaled and may be reserved exclusively to those who grow food for the newly socialized food industry.
The monetary system of the one-world government has more of a chance of being based on the EU model than anything else. How it will work is simple; each country has there own currency to trade in within the country. For inter-country trade, there will be a one-world currency to which each individual country’s currency will be weighed and measured. Right now currencies are compared right against each other. This leaves a power-vacuum that the world government can exploit. Expect the world currency to be lent out to industrialized nations heavily in debt by the time it is created; again, using the Fractional Reserve Banking System. This gives the World Bank more power to manipulate interest rates and international money supply. Then, expect the industrialized nations to phase out their currency in favor of the new world currency.
If you think I’m maniacal for including religion as a key part of a new government, take a look at this post on Faith-Based Initiatives. To sum it up here, faith-based initiatives are financial kickbacks for religious organizations that begin incorporating certain political ideals in their organization or organizations that put a religious spin on recent activities. So, the precedent is there, it has been done before. However, I noted before that this world government will integrate these pillars tighter than most industrialized nations do today. I will get to that in a moment. First, the focus of this new religion. There won’t be a deity. No God(s), no Satan. Instead, the entire new religion would be focused on Gaia worship; or worshiping of the Earth. Saviors would include the modern-day people who prop the message of Gaia worship along with those who contribute heavily to organizations that preach it (Greenpeace anyone?). This will allow the new government to appropriate more funding towards a GreenEconomy. Now, if I’m coming off as a oil-barren, I’m sorry; that wasn’t my intention. We do need to get away from most oil usage, including transitioning to Carbon fibers, using nuclear, solar, wind, and water current energy, dumping electric motors into vehicles, and promoting mass-transit. It just needs to happen, the oil usage cannot continue as it is today. But at the same time, I preach for practical purposes. I don’t care about “mother earth”. I view the earth as a mass of matter and energy, created by God, that all animals exploit. All animals eat, walk, run, lay waste, reproduce, and die. Their children do the same thing. We do it more because we have become the dominant species. Even if we were to scale down our energy usage and go more natural, we would still be the biggest consumers of mass and energy on the earth. It is and always will be. Green zealots are infuriated by this, and will always preach the message of energy consumption reduction and even population control.
