As a result, after drafting a youngster, we should:
(1) Fire him directly
(2) Train him and keep him forever
If train him and then fire him, will my training exemption get reduction?
There are other options too:
(3) Make sure your expenses fit within your revenues to not pay any tax and do whatever you want
(4) Do whatever you want and possibly pay the tax if you choose to exceed your revenues.
I still think that the benefit of training a player to be precisely what you want them to be more than exceeds an exemption that only comes in when you're overspending your means, but I suppose it's another carrot to encourage people to actually train their own players.
