a system, organization, or society in which people are chosen and moved into positions of success, power, and influence on the basis of their demonstrated abilities and merit.
Why not? The people most qualified should have the positions. The amount of qualified people and said positions probably don't always match and people may not want the jobs they qualify for though, But I think it's an ideal to strive for.
Just to make it clear the definition that I used does not talk about choosing people for tasks they are suited for, but rather putting them in positions of power, success, and influence.
Yes, but being good at something does not necessarily correlate to being good at managing others doing that thing.
This is especially pronounced in sales, where good salespeople get promoted to management, before immediately discovering that it requires a totally different skillset and they've basically changed fields entirely.
