It's because companies feel that if they spend money on training people then as soon as people get better qualified they will jump ship to another place paying better.

No, it's because they feel it isn't worth it and they'll figure it out on their own.  


It's not unheard for companies to go through high turn overs. I briefly worked for LG and they had a 96% turnover rate. But all they need is one or tow guys to start making that money.  


That or they run the place so lean they literally don't have anybody to train.
