You talking about financial inequality of the world but in my country there is problem of education itself. More than 30% of people don't even get the formal education and they are left out of the school when they don't pay fees for it. No free education as government is not stable enough to provide that too.
This has led to illiteracy a lot which in turn make these people to work as servants, low grade jobs, no respect and almost only that much payout which can feed their families only one time. This is shame and it's all because of internal factors of countries. Like politics, government, education problem etc.
The banks doesn't even count in the thoughts of these people.
Many countries are facing the problem of education, especially the third world countries. If I were to blame anyone for this, definitely it would be government but not the only the government of your country. The world of politics is full of unbelievable facts. Talking about banks under such conditions is actually ridiculous. But I am happy to see you here and hope soon more people of your country will be seen here.
