Bully Boy Bush and Barack Obama both oversaw it so it's bi-partisan.
And it produces so much 'actionable' 'intelligence.'
If you doubt it, peruse the FBI files.
October 28, 1966, for example, will reveal how the FBI saved the country by spying on film star Rock Hudson.
Rock Hudson has not been the subject of an FBI investigation. During 1965, however, a confidential informant reported that several years ago while he was in New York he had an "affair" with movie star Rock Hudson. The informant stated that from personal knowledge he knew that Rock Hudson was a homosexual. The belief was expressed that by "personal knowledge" the informant meant he had personally indulged in homosexual acts with Hudson or had witnessed or received information from individuals who had done so.

On another occasion, information was received by the Los Angeles Office of the FBI that it was common knowledge in the motion picture industry that Rock Hudson was suspected of having homosexual tendencies.
It is to be noted in May, 1961, a confidential source in New York also stated that Hudson definitely was a homosexual. (105-128834-73)
Money well spent?
The spying on American citizens is illegal and must stop.
