This is self-evidently true. One of the problems in current society is fetish for equity, the idea that everyone should be treated the same, regardless of their talents and virtues. Some people are smart, some are dumb. Some are generous, some are narcissistic. Those who are talented and virtuous are the one we need in charge of society. It is important, indeed essential, to discriminate: to prefer the smart and virtuous over the dumb and selfish.
"There is also an artificial aristocracy founded on wealth and birth."
Unfortunately, these are the actual people currently in charge of society. The wealthy, political elite - be it the Kennedy clan of Massachusetts or the Dassault clan of France - they wield the levers of power, sometimes openly and sometimes behind the scenes. Far from any feeling of noblesse oblige, they wield this power for their own purposes.
