Is it more important to be a leader or a follower?

It all depends on the person. If a person doesn't have what it takes to be a leader, it is more important for them to be a follower, because that's what they're good at given the two options.

Most people like the idea of being in charge, but the responsibilities and demands separate a good leader from a bad one. In order to be a good leader, you need to be a good follower first, so you have a clue about what you're doing.

Leaders can get more work, therefore more profit from an enterprise, because a group's accomplishments can be increased with a good leader. Sometimes 1+1+1 does not equal three, but four or more, if the group is organized and has a good leader, so a leader is more beneficial to an organization than  a follower, therefore has more compensation for his work, because his work produces more with less. These characteristice are not found in a follower, who may work hard, but not as effectively as when properly led, and consequently not paid as well as the leader, nor enjoy the higher status normally associated with leaders. Good leadership skills can be taught, but it helps if a person has been born with the natural tendencies, often found to be the case with many "type A" persons.
