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?
Tossing people out as a giant tech company after a profitable quarter is non-sense. They have money to be innovative, why are they choosing not to push that back into more attempts at products.
People expect bad news if the company gets bad news. If a company cuts after good news, people are going to lose faith in either their truthfulness (ie: are they cooking the books), their loyalty to employees, or both.
With that said, I would consider doing layoffs after a profitable quarter to be anti-social / anti-culture. It creates fear and uncertainty in the organization which will cause people to move to 'cash checks until I am fired then I'll leverage this to get a job somewhere else' versus trying hard to make the company their career where they put down roots.
In my opinion, chasing ever increasing profitability as a tech company is cannibalizing future earnings. By cutting over and over in pursuit of more profit, you are trading compound earnings (ie: create new products) for money today by injecting fear into your 'innovation centers'.
