It's ironic that the same companies who pay high salaries to attract top talent then go on to fritter away that talent through distracting work conditions, in an effort to save a few bucks on office space. Salary plus benefits are a much bigger yearly cost than office space for expensive employees like developers, so it seems like they're trying to optimize the wrong thing: if your employees are working at 50% productivity due to distractions, you'll never make up that amount of wasted expense on office space savings.

Also, the companies that complain about how hard it is to find qualified employees might consider that many of the most qualified people might not want to work for them because of their working conditions.
