That may be the classical view of management but is does not reflect the business environment today. Is Trump a "leader?" Today "leadership" is not respected in any environment and most managers do not have any correct qualifications, degrees, or experience. Study up on power-knowledge. Concepts: Power cannot be given to someone. It is created at the same time that it is asserted. Power is closely tied to knowledge monopolies. The usual way into a first management job is to follow a previous manager to a new company where the manager is getting a promotion. The manager needs allies and can't trust people at the new company, so brings along one or two as managers. Don't believe for a second that hard work or not screwing up will lead to a management position. If you think this you are not ready for a management position. For instance a lead dev I worked with screwed up a critical messaging system badly. He was already slated for a management job, so another dev was moved in to take the blame. This is what goes on in businesses as a matter of rule, not exception. You need to make some deals and show a propensity for management 'skills' namely bending reality and perceptions towards your point of view while motivating people to do things they don't want to do.
