This is one of the beauties of capitalism.
You don’t have to have the best grades, the highest IQ, or be the smartest person in the room.
You simply have to serve others with something that they willingly pay for.
(Voluntary exchange is the key.)
To the extent that you do this, you will profit.
And to the extent that you don’t, you will lose.
You can compete on price, or compete on quality (differentiation).
And you play with the same rules afforded everyone else.
For some, keeping Janis Joplin sober is all that is required for a season:
Sylvia was a tough but likable New Yorker who had moved west to enter the nightclub business and whose width, height, and depth were the same measurement. She didn’t know much about show business, having once told a ventriloquist to move the dummy closer to the microphone. She was, however, savvy about the bottom line, as evidenced by a sign in the kitchen that said: ANYONE GIVING MONEY TO JANIS JOPLIN BEFORE HER LAST SET IS FIRED! AND IF THEY ARE A CUSTOMER, THEY’RE 86’ ED!
