99.9% of the time, "deserve" applies to that which one has. Kind of like people who are confused about "respect".. they believe that when an ally tells them a truth they don't like, it is "disrespectful", and when a liar lies to them in a way they find pleasant, it's "respectful", when in both cases, the opposite is true.
A newborn hasn't "earned" what they have, but they deserve it because it is, and because their ancestors earned it for them. The wealthiest/healthiest people aren't people who at some point in their life learned a healthy diet, how to exercise, and to earn a high wage.. The healthiest/wealthiest people are those who had ancestors who sacrificed to earn, preserve, and teach, health/wealth to their descendants.
There are some people who spend money before they get it, and there are others who earn and save for their great grandkids who they don't expect to meet. The great grandkids don't earn their place when they're born, but their parents, grandparents, and great grandparents earned that place for them.
When people understand that IQ is inherited, and can't really be permanently increased (but can be permanently decreased through abuse, malnutrition, etc.), and that children require growing up in a family with married parents all living together to be healthy, their children will be far better off than those of people who don't realize those two things. If one lives their life accordingly, they will earn the several advantages for their children. It will be their child's to build from for future generations, or squander.
TL/DR; Elite backgrounds are "elite" for a reason. It is deserved, and based in merit.
