"Only a little while," replied the fisherman.
"Why didn't you stay out longer and catch more fish?" asked the American.
"I have enough for my family," the fisherman responded.
"But what do you do with the rest of your time?".
The fisherman thought about this for a moment. "I sleep late, then fish and come home to play with my children. We have lunch, and then my wife and I siesta for a few hours... in the evening I head to town and play guitar with my amigos while I drink a little wine."
The banker scoffed. "I could help you. You should spend more time fishing, and collect a bigger catch - using the extra money that you get from it to buy a bigger boat. With the bigger boat, you can catch even more fish - saving money by skipping the middleman and selling them directly to the processors. Eventually, you'll be able to use the proceeds to purchase your own cannery and control the fishing, processing and distribution of a massive corporation. Of course, you'll have to move away from this village to run the company - most likely to New York City. And, of course, you'd have to work from dawn to dusk to ensure it runs properly - but it's only for a while, before you're big enough and have enough people working under you to relax and enjoy your life!"
"How long would that be?" asked the fisherman.
The banker waved dismissively. "Oh, I'm sure we could get all this going within 15-20 years."
"And then what would I do?"
"Sell the company for millions and retire!"
"And then what?"
"Well, you'd retire to a small village in Mexico where you could sleep late, fish a little, and spend some time with your children. After lunch, you could siesta with your wife for a few hours, before you go in and spend some time with your amigos drinking wine and playing guitar..."
