There is some truth to what you are saying but that's not the complete picture to being a manager. You might shed some responsibilities but you pick up a whole lot more. The comment in this thread describes it better than I described being a manager https://news.ycombinator.com/item?id=19407800

You need to ask yourself how much you like mentoring people, spending time in meetings, playing the politics ... because those are the roles you pick up. Managers still have to explain why bugs are in the system even though they didn't write any code. I honestly think some people are wired for being managers and some are not. Trouble is some companies pay managers more and let them run riot with over developers.
