The Irish Potato Famine proved that charity is not adequate to save a starving population.
1 million men, women and children died from starvation and related disease. Another 1 million would have faced the same fate but fled the country. Under such circumstances, only national governments have the resources and logistics to alleviate such a problem but historically have failed.
The IPF and the abject poverty, disease and scarcity of jobs during the Great Depression of the 1930s in Britain were two of the many influences that caused the Labour Government under Clement Atlee to introduce the Welfare State by 1948.-

The wartime coalition , and the introduction of family allowances.[11] Many people welcomed this government intervention and wanted it to go further.[5]
The Beveridge Report of 1942, (which identified five "Giant Evils" in society: squalor, ignorance, want, idleness and disease) essentially recommended a national, compulsory, flat rate insurance scheme which would combine health care, unemployment and retirement benefits. Beveridge himself was careful to emphasise that unemployment benefits should be held to a subsistence level, and after six months would be conditional on work or training, so as not to encourage abuse of the system.[12] That was however predicated on the concept of the "maintenance of employment" which meant ‘it should be possible to make unemployment of any individual for more than 26 weeks continuously a rare thing in normal times’ [12] and recognised that the imposition of a training condition would be impractical if the unemployed were numbered by the million.[12] After its victory in the 1945 general election, the Labour Party pledged to eradicate the Giant Evils, and undertook policy measures to provide for the people of the United Kingdom "from the cradle to the grave."
"Included among the laws passed were the National Assistance Act 1948, National Insurance Act 1946, and National Insurance (Industrial Injuries) Act 1946". Wikipedia.
Today the Welfare State and in particular the National Health Service is generally acknowledged by all political parties and the British public as the UK's greatest asset.
Had such a system been in place in Ireland in the mid 19 century, a million lives would have been saved and a million would never have had to flee.
