But a big reason people only stay two years because we have had decades of companies gutting every incentive to stay somewhere longterm.

Whether or not companies should or shouldn't in their particular case is hard to answer generally. I am in an adjacent field to software and work on products that have lifetimes measured in decades. In that area short term thinking has been incredibly detrimental to organizations. I would also think investing in educating people that are going to work in an industry or are working in an industry will be a net positive to that industry. That is more a vibe based assertion than fact based though.
