Employee - Company's Most Valuable Assets

I think the most under-rated assets in a company is human resources, and also the most difficult to assess value. Most companies failed to comprehend this and I find they tend not able to go far or grow big.

I wonder is it their ego that caused them not to value employee other than themselves or that they just dun see the importance of it. In any case, to have staff resigning or failure to attract capable staff can cost the company their future.

I guess this is why Google provides such good facilities and working environment. After working with them, I bet no one wants to leave.
