Why are some countries still so rich and others so poor

[Daniel91]

If you really want to understand reason behind it study history, specially development of industry, trade, human civilization etc.
It's impossible to give simple and short answer here but basically western world used military power to conquer the rest of the world.
After that, they have used their raw materials and workforce for their own development and progress.

Historically, some countries have been held in slavery , if you take Africa , there are so many fossils that the continent could be the richest on earth , but there buy stones for a penny

With all the technology, healthcare and education why is the world still so divided? With some places being rich while others being torn in wars and crimes, forcing people to hide or become refugees. What are your thoughts on the issue?

Some countries have well knowledged leaders and also enough army and resources to become rich while other countries may lack some of it either resource or man power for managing their country.

Some countries compete for who is stronger, take diplomatic measures through organizations such as the UN, which in reality never do anything, poverty and hunger continue, politics makes dictators continue to exercise in the world, in their countries, without the other countries manage to deactivate such a hecatomb of society.

America found the secret sauce to capitalism by unleashing the potential of its people.  Other countries, especially Communist countries, limit their people’s creativity by controlling all kinds of freedom.  You are pretty much screwed if you are not part of the ruling Communist party.

Because rich countries know how to turn poor countries into money printers for them, this is the truth!

Culture... And maybe some random factors

[xen1oph]

Strange question. Because of the politics? Economy? There are too many options, all are obvious.

The rich country wants the poor ones to remain poor for a reason.

Because it happens that countries with advance living and economy has the advantage of gaining from other side of living.

And also that why there’s a classifications for each countries and the 3rd and5th world is the lowest of them all

The rich country wants the poor ones to remain poor for a reason.

Not that bad because sometimes it happens that poorer countries don’t wanna grow they are contented on what they have and what’s happening with them

History plays a great role about that. Countries which were rich 40-50 years ago are still rich despite the recent changes.

[akram143]

Politicians of poor countries getting richer and richer so their country is still poor even after all the development thing was made by their citizen.
