Phrmacy doctorate in my case was just a license to learn after being beaten to perdition and back on the killing floor. Took 15 years to actually deserve the hourly rate. Not complaining though... Didn't kill or permanently disfigure too many people in the later years of my career and consults. But please, be nice to your local pharmacist.
Fed A&P aircraft license was to die for fixing and writing off the mechanical labriniths. Big responsibility. Certifying that some dude can be up there beyond the survival crash limits and land safely in whatever he was flying. Earned some respectible bucks there, but your name is signed on to everything you signed off. Can come back to haunt you decades later.
Most important thing is that Bapu has some certificate. Proves that he is not no more igorant no more.
