So going back to the textile mill example above, what should the owner do? Keep the workers around even though they're not needed until the next recession, and only then fire them? If it's a particularly profitable industry, it might even still be profitable even with a recession, so is amazon on the hook for decades, until there's some sort of industry-wide crisis (think the one that hit the American auto industry in 2008), and by then it's too late because upstarts without the burden of older employees have already overtaken them?
