It's a very curious assertion to claim that "most founders are broke when they start off." That's contradicted by overwhelming evidence, at least when it comes to venture-backed founders. Musk benefited from his family's ownership of an emerald mine; Bill Gates' parents were both wealthy and well-connected (his mother's presence on the Board of IBM was what put Windows onto the IBM personal computer). Google's founders came from affluent middle-class families, as did Zuckerberg at Facebook. In fact, when we look at 1,000 of the most successful technology companies to have emerged over the last 50 years we see the same pattern again and again: successful founders come from backgrounds of wealth and privilege, which is how they have the ability not to worry about failure and how they can connect with influential people who subsequently ease their journey to success.
In short, the author's assertions about entrepreneurs are so wildly wrong that the entire article is worthless.
