And Ireland’s population has never recovered to what it was before the famine, even after 150 years.

Literally the ideology that made the Irish potato famine. The whole time the famine happened, Ireland was exporting food to England. And the English refused to give aid because it’d reward those pesky lazy overbreeding Irish poors. When they did send aid they refused to send milled corn so that those lazy starving Irish had to WORK for their damn corn gruel!
