Answer:
Governments and powerful people from a few certain countries, including Russia, China, and the United Arab Emirates.
Step-by-step explanation:
We can see men dressed in specific clothes behind people from oil companies. From the clothes, we can deduct they are from Russia (flag on the jacket), China (flag on the helmet), and the middle eastern country, likely the United Arab Emirates (traditional men's clothes from the country). These threatening and menacing figures likely represent powerful chiefs from the said countries and their government.
The cartoon, therefore, tries to say that the money, goods, and control over the oil business are held by the governments of certain powerful countries that are behind the monopoly, including Russia, China, and the United Arab Emirates.
