I've watched this process with my brother, and with coworkers in my own industry. In my brother's case, he was at least given a cushy "early retirement" buyout package. But because of some old debts, he still needs to work, and he found it exceedingly difficult to find a new job (admittedly right after the housing crisis), despite having a very easily transferable skill-set . When he did find one, it was at a much lower level of responsibility (and pay); in fact he started out as part-time and had to wait for a full-time opening.
In general, it seems like workers in their 50's tend to get pushed out as soon there's a hiccup in corporate budgets. They're prime targets because they earn the most, and because it's assumed that they won't/can't adapt to new job requirements or technologies. But of course they also find it very difficult to find new jobs for the very same reasons, plus the assumption that they won't be around very long anyway.
One of the reasons I follow this forum, despite the fact that I enjoy my job, is that I want to have the reserves in place to be able to exit the workforce gracefully if I'm pushed out after age 50.
