Why was the Spears family so prominent in her prime?

[Psammead]

Lynn liked the attention and Jamie liked the money.

On that interview that Bryan did, he referred to "our" business, giving the idea that the Spears family considered "Britney" a Spears project.

Someone said after the interview, and it's fair enough, that having someone like Britney be such a success, in such a crazy business, takes a toll on the family, who go through a lot in the early years. Suggesting somewhat like a hockey player or other athlete, where parents sacrifice a lot and it takes a toll on siblings.

It doesn't explain the zeal with which they pursued her life, or why they don't read the writing on the wall now. Spears' gonna be Spears.
