It is interesting to note that the potato blight was not limited to Ireland. It struck also Germany, in particular Saxony and Silesia, and impelled a lot of Germans to emigrate. But it was not so horrible there as in Ireland. The Irish problem came in large part from the kind of "Economic" thinking that says, whatever the "market" does has to be right. This although the leading English economists of the time, John Stuart Mill and Nassau Senior, strenuously protested that the policy was wrong.
