Thr famine can also be looked at as a class issue, the grain harvests were good, but the poor could not afford to buy bread. Thus grain and other crops were exported and some farmers continued to prosper. The peasant classes relying on potatoes suffered horribly.
The concept of famine relief and humaitarian aid was not well developed at the time, and was also an ethnic divide that made things worse, especially in unsympathetic reports being published in England.
