But...
1) even the hardships by old billionaires seems to be temporary or brief, i.e. Warren Buffet finding a way to make thousands of dollars through his paper route at the age of only 15
2) The writer provides a single instance of a 'boring' young billionaire, being Mark Zuckerberg
3) The writer provides multiple counterpoint examples to the thesis in the text with Elon Musk, Jeff Bezos, and Sergey Brin as being tech billionaires that came from nothing.
I wouldn't be too surprised if there wasn't some truth to the thesis (although 'boring' is a loaded and subjective term to begin with), but the writer does a terrible job at defending their position.
I'm seeing a lot of these poorly written articles lately. Journalists have a preconceived point they want to make, make it in the headline, and then pretend they're writing something that supports it but not really supporting their thesis at all, counting on the fact that most people are only going to skim the article and not critically evaluate it so they can put their idea into people's heads 'Hey, young billionaires are all totes boring, right?", inception style.
