This is an interesting survey. I wonder how would this look if it is in India. My experience in training and mentoring people who are either managers or aspiring managers indicate the following:
1. The percentage of people aspiring for the role would be very high may 80% plus. This is also because in Indian context we see a lonk of remunerations and status attached to leadership roles.
2. Interestingly I do not find people actually realize what it takes to be a manager. The interest is more from “other side of the river is greene\” perspective.
I say this because most want to become manager, but when it comes to investing (in form of efforts to learn and build capability) is pretty low. I also see that often training is considered to be panacea for this. In my view, training is possibly only the first step but by itself does not guarantee learning and related success.
