Unfortunately the systemic incentives support PIs that are basically hype salespeople. PIs gain prominence on metrics: number of dollars raised, number of PhDs mentored, number of post-docs on staff, number of papers landed, number of awards granted... They are not supported on number of hours of research done-- they arguably put in that time when they were PhD candidates or post-docs themselves. When I was a PhD candidate (couldn't handle the papers-or-die academic environment so I left) I really, really loved my PI. He had immense academic and intellectual humility. But even he had 10+ papers in-flight at the same time and rarely had time to do any work himself!
