That’s why the “hustling culture” is so important and prevalent in our society right now.
Everyone “knows” someone that made bank with either youtube, selling some pyramid-scheme product, bitcoins, some collectibles, craft beer, lottery… you name it.
Social media (and before that was TV) is selling us the idea that there’s a shortcut to becoming rich, you just need to find it, hustle, and you will become one of the rich persons.
That’s also why there’s so much cult of wealth and billionaires.
That said, a large portion of Millennials and after them have a rather negative view of billionaires and are rather skeptical of becoming rich, or even becoming home owners.
