> avoid hiring people who jump companies every couple year

You don't get many of those people any more, because just about every other employer has burned that bridge to the ground. People, especially the young ones who entered their careers around the 2008ff megacrisis, have zero trust left in anyone.

When companies don't care and ditch us at the first sign of problems (easy, because we were the freshest hires), why should we show any sign of loyalty in return? If you want loyalty, pay us.
