I'm not sure most people get a medical degree to "obtain one suitable mate and have a few offspring". I think most people do that to be a medical practitioner.
You could say people want to be medical practitioners because they want to find love and start a family but you could also say they want it because they want to be comfortably wealthy and financially secure.
Yes, but that's why this is a hack. Smart enough to not want to take care of 100+ children and child support, and you even get paid by the people who take care of your child for you.
(Not saying it's moral, hacking may or may not be moral.)
