He's pretty much saying that all problems in your company can be traced to people. I shared the same concern, but having heard Ries speak in the past, I think his use of "people" here is a bit misleading. A commenter on the video made the good point that it's probably more accurate to refer to "process problems" than "people problems". I think this video may have been flavored by his audience, looking down from an upper-management perspective. "People problems" implies that you need to keep people from messing up. "Process problems" includes more institutional problems: culture, training, scheduling, prioritization, &c.
