The famine was prolonged and exacerbated by your own Irish landowners and aristocracy.
I was tempted simply to keep my 'wah' shield up as it's quite clear the nonsense you are promulgating is just a big wind-up but given the number of informative up-votes you are receiving it appears there are many credulous eejits who actually think what you are stating is historical fact, so with reluctance I must step in.
The ruling Anglo-Irish/Protestant Ascendancy, call them what you will, landlord class in Ireland were "Irish" in the sense that the Afrikanners of South Africa are "African". They adopted an Irish identity merely in regard to Ireland's position within the United Kingdom ie with regard to the protestant Church of Ireland, the British Army's Irish regiments, Irish cricket or rugby teams etc. but in all other respects regarded themselves as a race apart from what we might describe, for want of a better term, as the indigenous Irish.
They filled the same role as any colonial planter class around the world, they lived a luxury life, cultivated vast estates, extracted raw agricultural commodities and provided militias for the imperial forces when the natives got uppity. The only exception being that they shared roughly the same complexion as their colonised population.
They were Irish in the same way as French or British rubber plantation owners were Vietnamese or Malay. They owed allegiance to the imperial dynasty, they lived a privileged, rent-seeking life-style, they were reactionary, resisted all attempts at national self-determination and were often vehemently opposed to any attempt by the metropolitan government to ameliorate the living standards of the natives.
To give a few examples of your so-called "Irish" landowners and aristocracy.
During the famine it was pointed out that a village in Lord Palmerston's estate in Ireland had been evicted and sent off to America. Palmerston pleaded a lack of knowledge of this incident and explained that his land agent handled these matters. Now we will pass over whether it is conceivable that a British Foreign Secretary would have been unaware that a village in his estate in Surrey had just been sent packing to America during a dreadful famine and simply ask whether anyone seriously believes that Lord Palmerston was a great "Irish" statesman?
Lord Lucan, you know the nanny basher? Well as his name suggests his family has a fine Irish estate around Lucan in County Dublin. I have yet to hear anyone refer to Lord Lucan as a famous "Irish" fugitive.
Charles Stewart Henry Vane-Tempest-Stewart, the Nazi-appeasing British Secretary of State for the Air during the 1930s, educated in Eton and Sandhurst, lived in eye-watering opulence in his beautiful mansion in Mayfair. The name of the home, Londonderry House, would be a clue to the source of his vast wealth. Are you suggesting that the "Londonderry Herr" was in fact a closet Paddy, a DeValera stooge, inserted into England to undermine imperial rule?
