They could offer to retrain these people in new technology instead of just laying them off and hiring new people. I learn at least one or two new technologies with every job change I make, and I'm not even usually given formal training. With formal training policies I'm sure they could shift employees to other projects and then keep their domain knowledge, but because they're old and more expensive than the young'ns, we'll just claim they don't have the skills for the new jobs and lay them off instead, and save that money! Domain knowledge and experience is criminally underrated nowadays. A company I've worked for is currently going through one fire after another constantly because the executives haven't valued domain knowledge and has forced or outsourced just about everyone who knows anything about the projects that they still have paying clients for and need to support to keep making revenue, and things are just barely not falling completely apart (looks like things are going to get worse here pretty soon though). And this isn't even ageism, really, even the young devs that have only been there a couple of years are being forced out.
