@Cowboy is correct though. The wealthy who do that didn't do that in a day—globally speaking, most of them come from generational wealth. The tech giants are admittedly nouveau riche, but, like oil giants yesteryear, they hit upon on an emerging natural resource at the right time and place and monetized it. Neither of those are easy to replicate.
