That's a tough nut, but I'll take a stab.
I hope
@kiddiedoc will weigh in on this one.
Preventative health care is difficult to quantify because if you don't get sick, how do you know WHY you didn't get sick? So going to the doctor 'all the time' as you say (and I know what you are getting at actually, and this is not really the argument here) results in being 'less' sick, then you have saved money by not requiring further treatment. That translates to fewer medicines required which saves money (big pharma doesn't like that though). A GREAT example is the debate between Ivermectin and the ClotShot. Ivermectin... cheap and readily available. Not much profit/cost. ClotShot.... expensive and initially in short supply. When the panic mechanism was triggered among the weak minded by a president hating/complicit media... big pharma cranked up production and made lots of money off of the .gov. And the hidden gem in ALL of that was: wash your hands, don't touch your face and if you are sick, stay home. Cheap, effective and unquantifiable.
If we had only known that was an option to begin with...... <- sarcasm
