"I know how to make piles of money while sitting on my ass" (without being a psychopathic CEO, a crypto bro or a "fintech" con artist, for the sake of not hating myself)
Then I can use my money to buy the services of anybody who has the other abilities I need while still sitting on my ass, and feel good providing employment at the same time.
The problem is luck plays an enormous role in whether or not a company fails or makes bank. This is how we end up with idiots who become hundred-millionaires or billionaires. Though being savvy helps improve your chances.
If you're good at playing the dailies, you will inevitably go bust, possibly while owning a bunch of rotting commodities that didn't sell in time, but once you have a reputation friends will lend you money to get back on your feet (which you pay back with interest.)
"Contract management", I think it's called.
You hire the services of one factory or laboratory to do your manufacture and packaging, another company for distribution and marketing, another for accounting, etc. You can build a good-sized company with one employee: You, the owner.
