“But how much do you “plow” back in? When is enough, enough? If you develop a successful business, your employees will run it for you.”
You plow it back in as long as it is creating a profit and jobs.
And what do you do when your profits are in the billions of dollars? How much is enough? How many yachts can you ski behind? How many mansions can you live in at once? How many private jets do you need? Like I’ve said, at some point you have enough and it’s time to start giving it away.
