In Ireland at the time, food was actually being exported out of Ireland while people starved. So it was starvation not only because of food loss, but also because of politics and repression–very much the same situation that exists in parts of Africa and in Yemen–and only politics could ultimately change the underlying conditions in Ireland.
There was that time when Manifest Destiny was being pursued, people were moving West. The areas West were not actual States within the United States. There was a lawlessness. People were yearning in those territories to be States so that they could count on the Federal Government to provide fairness–ultimate fairness–and provide a life that would be lived under the United States Constitution. They felt, in those days, if we could just get the Federal Government to have a Federal marshal here and a Federal Court here, wow, life would be so much better. Now we have seen it has lived beyond the usefulness it once had and has become quite a burden to overcome in reaching fairness and constitutionality.
