From the article:

"Why is hiring so tough? Because talented people don’t need you anymore. They don’t need the benefits because they know if worse comes to worse, they will find a comfy job. The options are there for them, therefore the risk of starting their own company isn’t an all or nothing deal."

While this has been true for years, I think, more than ever, talented and driven people are realizing that a comfy career isn't an aspiration but a fallback.
