A good pediatrician will do this. They can identify issues like varicocele that is stunting the growth of one of your testicles and recommend follow up which your parent can then ignore until you complain as an adult of an achy ball to find out it’s 1/3 the size of the other and the rest of the mass there were veins which when cut out instantly relieved the symptoms and laid bare your shrimp ball that was choked out and its lost opportunity for glory.

Yes. For those who consider it wasteful spending, consider that a lot of problems are not fixable by just throwing more money at them. There’s a saying that “9 women can’t make a baby in one month” even though 1 woman can in 9. Many ills of society are as much about political/social motivation, entrenched opponents/regulatory capture, NIMBYism, etc and not problems that you can fix just by spending more. There’s also the concept of a “marginal dollar” - spending one more dollar in an important area that already has a lot of money (and has problems that aren’t really addressed by just having more money) may not be as impactful as a less important area where that dollar would go a lot further.
