Watch the Price of GOLD!

[Baron Von Murderpaws]

How would we ever have doctors without money? They'd be too busy growing their own food to study a book.

No.
Again, the bartering system.

They work as apprentices in medicine until they get their degree.
When they get their degree, they have not only learned by hands on, they've learned the literal knowledge they need to do their jobs right.
As long as they stay in school and agree to become a doctor for the commuity, the community would see to it they have a place to live, study, and food to eat.

There is no need for money.

Kinda wishful thunking wouldn't you say?

If someone takes you to teach you how to trade crypto, stocks, forex, binary options, etc., it means that he expects to earn more from you, than he can make on these instruments himself.
That's all you need to know about such courses and teachers.
