There's a 3rd reason: In my experience, tech employee turnover is often directly related to corporate/executive turnover. You can hire into the most forward-thinking, technology-valuing workplace and then find that a merger, acquisition or management purge transforms your company into a hide-bound, change-averse organization that suddenly sees research as an extravagance and development as a red-line expense counting against the bottom-line.

I've seen this devolution happen at least three times in my career at three different companies. In every case, it results in devaluation, then exploitation, then burnout of previously enthusiastic, talented developers who soon leave. Sadly (even if you are a staunch capitalist in the executive suite) this "streamlining" almost always proves misguided as the company inevitably loses all technical credibility, innovation stalls and it loses any competitive edge it might have had along with market share.
