Sorry that's just whitewashing of British behaviour in Ireland, while I dislike the Plastic Paddys the behaviour of the British in Ireland can't be described as benevolent, for one thing while the Potato Famine wasn't deliberated (in the same way the famines in Ukraine wasn't deliberated), it was worse than anything Russia did to Poland, if we look at the population reductions, it was worse than anything that Germany did to Poland
In fact, there was no famine in the strictest sense; even the Irish expression for the period, "The Great Hunger" makes the point. Ireland's markets were full of produce in the years 1846-9; however, there was an unemployed underclass with no money to buy this food. Unemployment in Ireland hit 25% during this depression (and it was a Europe-wide depression).
Ireland in 1810 was a rich nation, with a typical European income level. Ireland in 1840 was poor in parts, because the population boom had caused the very bottom rungs of society to become dependent on sustainance agriculture, earning no income beyond the small excesses they sold. When their primary crop failed they couldn't buy food (which was rapidly heavily subsidised, with some nasty knock-on effects), they had no money. They could go and take employment on the public works, but that would mean abandoning their small plot of land. Eventually the government gave up, and simply started handing out food. They laid a large part of the bill at the Irish landowning class for allowing this situation to develop in the first place.
One of the knock-on effects of the subsidy was that food prices in Ireland halved during the famine (yes, food got cheaper since it was far more abundant in the market, supply and demand). This hit the smaller Irish producers who saw their income half as a result. The result was it became increasingly difficult for a tenant farmer to turn a profit, at a time where HMG was squeezing their landlords to pay for the crisis they'd allowed to occur. Tens of thousands ended up defaulting.
The net result is a lot of emigration to find work, and an often exagerated number of excess mortalities (bearing in mind Ireland was on the downslide of a population boom, the crash, even before 1845).
I'm still not sure what HMG were supposed to do. The amount spent on famine relief was 10.5 million pounds between 1846-9 (a line in the budget approaching the Army Estimates, which were around 6m pa, divided over the 3 budgets of the crisis, we see HMG on average spent a sum equal to half the Army budget on Irish poor relief). Even this wasn't enough.
