Do most agree? How do managers see their jobs - more money, better job security, retirement job, etc.?
I've been a manager at other companies and if done well it's a harder job than being an individual contributor(1). Ages ago when Cisco was still growing significantly I was offered a management role and I immediately declined because at Cisco it was obviously a pointless 360 degree battle to the death with no prize rather than 360 degrees of cooperation to grow the revenue, income, skills, etc... of all involved.
For the record I saw Directors and even the occasional Distinguished Engineer sent off to spend time with their family starting as early as 2001, so there have been pockets of accountability.
(1) For some sets of requirements there is a nice black and white "you got it right" or "you got it wrong" on the technology side. In business the risks are driven by dozens of unpredictable forces over which you have little to no control. If you look at the research on successful people they're almost never the brightest - luck is the defining characteristic for their success. If the risk of being laid off is hard for you, understanding and living with the forces that could quickly result in everyone who reports to you including you being laid off and knowing at best you can only influence them will be far more difficult to deal with.
