Statistical metrics are difficult and critical.   Without date, decision making become little more than guesswork.   

 Metrics can be distorted by intent or by human error. That isn't a reason to discontinue to data analysis, it just mean you need to have skilled trustworthy managers, not political appointee's in charge.   

No corporation would arbitrary cut 20% of their accounting department.  You can't know your performance without a measurement.    National data that directs federal funding must be accurate.    

My concern is that those that don't have the interest, or the ability to collect and analyze data will simply call it 'fake data' when they don't like what the facts are saying.    Those who deny the facts will try to discredit the source, most likely accusing those groups of trying to find ways to collect public tax's.    

Absolutely, we should take a fresh look at old processes, but we should expect proof that they don't serve a useful purpose.
