not many people [and that includes HealthCare Professionals] know what NORMAL blood sugars and Hb A1cs are. That's why they seem to be satisfied with the numbers that they are.
Normal Blood glucose, usually runs from about 3.5 to 5.5 and rarely goes much above, even after a carbful meal,although they may drop o 3 or just below without ill effect. I have read reports from people claiming numbers up to 8 for non-diabetics. I suspect that those people have slightly impaired glucose metabolism and are probably related [and share genes] with diagnosed diabetics.
Bernstein quotes that he tests any willing sales reps that come to his office. He challenges them, by saying he knows what their BG is. He gets away with it too, because he always says 85 [that's 4.7 in our numbers.
It's much more difficult for insulin users, but it is posssible to keep to non-diabetic numbers.

It's my personal opinion is that there's far more damage done by persistent high sugars than by hypos, however unpleasant they may be.
[And yes! anyone who wants to jump on me I HAVE experiened a severe hypo quite recently]
