Unfortunately, multiple countries (including any one of those you could be depicting as a fat white guy in this picture) have been sending billions of dollars in both aid, supplies, volunteers, teachers, and technology (like mills, water cleaning devices, etc) in an effort to help countries in places like Africa for a long, LONG time--and yet no change has happened in the past century. In fact:
Top 5 Countries Labeled "Most Generous" in 2015 (based on government foreign aid and not including individual donations from everyday people):
1. United States (over $30.76+ billion)
2. Germany ($20.85+ billion)
3. UK ($19.92 billion)
4. France ($10.9 billion)
5. Japan ($10.4 billion)
(followed closely by Sweden, the Netherlands, Norway, and Canada)
While I can't speak for the other countries, in 2015 individual Americans, companies, and foundations outside the government aid also gave about $373.25 billion to various charities in and outside the United States.
It is a cruel stereotype to see your own people shown as fat, greedy, ignorant, rich, selfish slobs when you live in a society that is ALWAYS thinking about other people--how to feed them, how to clothe them, how to help them after disaster, how to not offend them, how to comfort them, etc. I've grown up around people who I've seen give even when they have little to give--far from being rich. My family was laid off a few times when I was a kid because of hard times, and my father came from a dirt poor family that could see chickens running under the house through the floorboards. He had to drop out of school and work on a tobacco farm to help feed his mother and five siblings. The people I know are hard working. They wake up before dawn, go to work, come home exhausted, and don't have pockets full of cash--but they still give when they see a cause. I think that's true for most normal people in all the countries stereotyped as "1st world" countries by the modern media. It's not really fair to show a big, fat white guy eating pizza with a TV remote and staring at the starving man with contempt as illustrating the main problem as to why Africans (I assume based on the illustration) are poverty stricken.
The reason why Africa and other starving countries are they way they are, as sad as it is to say, is because of their governments. What's happening with those trillions of dollars multiple countries across the world have been pouring into developing countries over the past decades? In fact, people have been trying to get Africa developed for centuries with no luck--despite the fact that Africa is RICH in both land and resources beyond imagine. It's their governing systems. These poverty stricken countries are some of the most oppressed and corrupt countries in the world. They take the food from their own people's mouths. A poll in 2016 given to various people across Africa showed that 58% of Africans say that corruption within their country is getting worse. Their nations center on bribes--meaning police officers are paid to ignore crimes (including rape), or people paying bribe money just to have access to basic supplies they need to survive that are otherwise withheld from them. In 2014, 75 million people across Africa paid bribes (to give you an idea of how many people that is--that's equivalent to 1/4 of the American population). In addition to this, modern slavery (forced labor, selling children, sex trade, and ritual slavery) is still very much a problem in Africa as it has always been--even in countries that claim to have ended slavery. These problems don't even include the growing number of violent, mass murdering terrorist groups who are intent on preventing girls from going to school and subjugating entire villages and regions to convert religions and obey their laws or die.
It's their corrupt governments and rampant terrorist groups that unfortunately grip their societies and cause their people to live in abject poverty and fear. It's this that robs them of basic human rights like food, medicine, education, and prosperity. I'm not saying that we should stop giving them aid. However, we do need to STOP saying that all the problems in the world are due to other countries' successes. Harmful stereotypes like that only make the problem worse and divert everyone's attention from finding a real solution--thus dooming those who are suffering to continue living in the same, or worsening, conditions.
