I once worked somewhere that took it as a given that developers left after 18 months. They were susceptible to the effects (developers leaving for higher salaries) but their response was to accept the turnover rather than to change. Their primary offering was not software and their profits grew almost every year, so they had little incentive to make changes: especially ones whose pain is immediate and payoff is harder to quantify.
