John T. Walton became rich through inheritance.
Ergo, there are ways of getting rich other than providing value.
Ergo, looking at someone who is rich doesn't tell you that they provided value.
Just the facts.
Suppose you have more money than you need and want to be charitable, so you set up some terms under which you'll give some away. A scholarship fund, a shelter, whatever you like. You can set whatever criteria you want, because it's your money.
But then you could also use the criteria "the people who get this free tuition money and housing are your kids." Being able to do this, benefit their kids, is a primary motivator for parents to work to make more money.
And if you can give away the money to anyone you want three seconds before death, it makes no sense to say you can't sign a piece of paper to that effect at any point prior either.
If we want any sort of system even approaching a meritocracy then you should not be able to will away such vast estates that people can control entire companies or never work again a day in their life solely off the inherited assets
personally I find it pretty reasonable that I get to decide who gets the lion's share of assets I have worked for my whole life. at the same time, it seems bad when enormous amounts of wealth are passed down over generations (and having known a couple people in this situation, it seems bad for them too). the question is, where do we strike the balance?
If someone doesn't expect to live much longer but can still provide a significant amount of value to others, their incentive to do it is that they can decide how the money gets used, i.e. they can give it to their kids or otherwise choose who gets it after they're not around to use it anymore.
Take that away and you take away their incentive to earn money they soon won't be alive to use themselves, which is a huge distortion.
Meanwhile people starting off with money allows them to use it, but that doesn't imply inefficiency. They don't lack the incentive to use it for something productive.
This provides a definition of a market distortions:

This may help understand why it is defined this particular way and why it excludes inheritance and other wealth transfers:
