Because people have children who benefit from their resources without having done anything to earn it, because those in power (having wealth of one kind or another) can leverage that power to suppress the ability of others to attain it, because no one is free of biases, etc. Honestly if you can't see how the ideal of a meritocracy is impossible you're just not trying. Surely, some elements of meritocratic ideas are useful, but it is folly to believe that people with wealth have 'earned' it purely on merit.
