I can only see it as a cynical practice and ironically a poor use of time.
Cynical - Following another's trading style is notoriously difficult so most of the trainer's students are paying through the nose to learn how to fail. By all our previous experiences, the more complex courses will appear to be better value, more condensed, more technical (not just silly MA crossovers) - but that just makes the trading they contain even more difficult to replicate profitably.
Poor use of time - If you can make money trading, do it and if you need more, trade more: if you can't do it, you don't deserve to be teaching it. If youi're making enough and can trade less, spend the non-trading hours properly - in the pursuit of selfish enjoyment (or doing some charity work).
i don't disagree with your points, other than poor use of time. I'm not interested in the moral dilemmas of training, its answering the question why would you if you really could trade.
Like I say if he wasn't trading, what better use of time is there, than increasing his ability to generate more
I work for myself, have a great daily rate..if I wanted to earn more, I'd have to work more. That might mean weekends. That's not a clever use of time.
Now, if I was really clever, I'd train people to be able to do what I do, subcontract such that other people would do the work for me at a cheaper rate and I'd benefit. AND, I can still go out to work myself or pursue the nobler charitable duties and not worry about missing out.
Does it mean I'm not successful at doing what I do? Of course not, I've just found a way of increasing my revenue streams regardless of how good I am
Working more yes can help, but its about working smarter. Its not about having enough, its just about being able to do the exact same and still be better off.
now, being really good at what I do, helps. I have a reputation, should that suffer, then my potential to generate that income suffers. So does the trader, but thats a completely different issue. for a time, however limited he is able to generate two sources of income and still carry on doing what he was doing. Thats good business sense
