Imagine live is a game where everyone gets a fair coin. One flips it whenever anything not under bones control happens. Being born on LeapDay is like having a biased coin coming up heads 51% of the time. Over the course of a lifetime, this can more than double one's earnings.

Obstetricians will induce labor for making certain that children are born on LeapDay, thus giving them an enormous advantage.

¿What if one's parents have the self-deafeating habit of not wanting to be noticed and want their children to be born on February 28th instead?

The greedy obstetricians, in violation of medical ethics, wordless take the money, as they do for sexually mutilating nontherapeutic the genitals of defenseless babies, and induce the labor on the 28th of February, thus screwing their patients out of more than half their future income. Ethically, they should refuse, explain to the parents that they would screw their child over for life for dissading them from going to a less ethical obstetrician, and offer to induce labor on LeapDay instead.
