The Irish were once drowning migrants too

That’s as bad as it gets.
Back in the late 1840s, they had coffin ships. Desperate people crammed-on, packed-off, consumed with dysentery and typhus. One third of these desperate people died en route, with so many bodies thrown overboard that sharks followed the ships the way seagulls follow trawlers. In 1847 alone, one fifth of the 100,000 Irish people who left for Canada and North America died before they ever got there. We know all this from our history books.
