"The story of a simple sum"

The eternal story of the conflict between labor and certain creditor. The majority of the people depend on the river predatory fish. They took risk life in the middle of the sea at hole night and came back to the coast in the morning with fish and they sell fish to certain lender with very poor price but within short period of time the fish sold with more price and full of pocket with profit money. The rich are became richer and the poor are poorer every day. This is not only happening in Bangladesh. The around the world, and almost same the picture.
