I don’t. There is a limited amount of wealth in the economy at any given moment. There is also a limited amount of well-paying jobs, which can lead to social mobility, and there is also a limited amount of wealth for investing in new ventures. Since these things are finite, one person being 20x richer than you or me means they are sitting on money and taking opportunities that others cannot. Time and money are not infinite because Earth’s resources are not infinite.
And yes, Zach Dell alone being wealthy or taking a lucrative job does not substantively affect everyone’s wealth. He is just one person. But I hope you can realize that the author is employing a literary device known as an anecdote or an example to start off their piece in order to illustrate a larger issue, which is that the wealthy are able to get opportunities and more wealth just by virtue of what family they were born into. Whether this is a problem or not is up to you, but I think reducing the article to “overtones of jealously” and “mediocracy” is misleading, although in an unintentionally amusing way; the author is actually calling out the blatant “mediocracy” that is inherent to privilege in our so-called merit-based society. I think this is a valid issue to write about and discuss.
But yes, let us thank our benevolent masters, who throw pennies from their high castles at us commoners as we bow and scrape for their favor. Nothing to see here, folks, poor children get potable water and rich children get seven figure salaries! What inequality and nepotism do you speak of?
I have a really hard time believing someone else's fortune means that I cannot also be fortunate. I find the premise of articles like this sad. It's riddled with overtones of jealously, mediocracy, and comparison (which is the thief of joy).
