Re: Just to play devil's advocate here
then you would expect 60% of layoffs to be of people over 40.
Except that it's the people with greater knowledge and experience who tend to survive layoffs, because most rational businesses recognise that they need those people most when they are under pressure. When the business recovers or the market expands once more, the business can quickly build up their numbers by hiring and training up young people from the large pool straight out of university.
