this is not a farm system. You dont own the team you are sending him to. You can send him to another country. It is for lower teams to get better players and help them with out paying their whole salary and you get your 18 year ols 2nd round pick aa chance to play and prove his worth to you before you decide to sell him. This idea works even better if there is a cap on how many players your team can own.
You got to know when to hold em, know when to fold em, Know when to walk away and know when to run. You never count your money when youre sittin at the table. Therell be time enough for countin when the dealins done.
