To get started, we have to look at the history and the way capital has flowed between nations.
Some countries are all about commodities like oil, gold, and various raw materials. Think of the Middle East, China, Russia, and parts of Latin America (including cartels). These regions are pretty much the main suppliers of commodities globally.
On the flip side, you’ve got nations that provide luxury services to those commodity-rich countries. They offer them ways to invest in property, banking, financial services, and high-end experiences. Places like the UK, especially London, Switzerland, France, and Monaco are the go-to spots for the wealthy looking to spend.
Then there's the USA, which essentially manages the global financial markets. They’re focused on tech, telecommunications, and ensuring that everything runs smoothly worldwide like making sure the internet and financial systems are stable.
Now we’re at a point where the USA has recognized that these "luxury service nations" don't really give back. They’re not contributing anything to global efforts, like NATO, despite the wealth they’ve made from rich nations in the Gulf, Africa, Russia, and China. So, the USA might just decide to cut ties and leave them to fend for themselves. Honestly, countries like the UK, France, and Switzerland seem to just be fancy butler services for the rich, especially London where everything comes with a ridiculous price tag.
Honestly the truth is that the world economy isn't that straight and countries do overlap, there are countries that have oil and at same time they also invest on tech while those that have finance and strong industry service still produces, they all contribute ls and innovate to the global system. Is like or as if it's one nation or group that serve and the other supplies they're all connected and every region depends on each other to grow
Even if any country is strong in power or technology it still needs another country in some way or the other.To fulfill this need every country is connected to each other because each country has a specific product.To obtain it one country trades with another country and such an economy comes into existence.Due to trade countries solve their problems and develop. This also shows that no human being or economy can be managed alone.In some way or the other we need the help of others so that the problems can be eliminated and the country can develop.If we do not help each other the economy will deteriorate and it can be difficult to manage.
If we doesn't help each other then that is the end of humanity, the countries need each other in one way or the other, because some countries contain different kind of resources that is required by other countries. Depending on how much people care about one another, and the stability, growth and the development of every country. I believe most of the things that is affecting some countries now is corruption and people are failing woefully to address the issues. If their is possibility governments shouldn't overlook the import and export of goods and useful resources, I believe this exchange can take the world to great lengths, but some people are using this opportunity for their own requirements and benefits.
United we stand, divided we fall. This shows that a tree cannot a forest because it not going to survive the hash weather. Countries need each other to trade and survive in the long run because each country natural resources and area of specialization differs from the other.
This is why you see that we have UN and BRICS because you need to be part of a group with the same vision to help each other grow together, defend and fight for each other when being attacked by the enemies.
Yes, we need all of us together, otherwise it is not going to be okay. One nation can't be self sufficient in everything, sure some of the things could be true, but not in EVERY thing, so you need other countries to trade and make sure that you have access to some other stuff.
This is why we need to make sure that we are dealing with peace, and not war. Whenever there are wars around the world, that means terrible for the economy of every nation, even in the nations that are not in the war.
Even the most powerful countries needs the partnership from other countries to effectively work well with especially when it comes to the economic development and stability of such countries. The last time I checked countries like the united states, China, France Russia etc rely on Africa to get the raw materials that is needed to build the technology that they are bagging about today. If Africa refuses to supply the needed raw materials to Europe you will find out that it will not be good for their economy.
