A situation has come to the attention of the Chinese government and others that families are sending sound bodied kids to monestaries while they keep those with minds the europeans like whose bodies will give out after going through the rigamarole set out to test if they are worthy of a wage for their labor with the intention of using the kid in the monestary for spare parts.
When this occurs in China, that is when the monks end up in mental instatutions, because the government feels they are crazy and a threat to themselves to be willing to give up their life to help someone else be a slave.
In other places we have been cultivating tigers to support our right to refuse service in such situations. However, in cases where people have come into our debt, and the donor in question is capable of providing a service equal to the others value, we are still not so strong that swapping is beneath us.
*My family and I made the concious decision for me to perform at the capacity possible when only repairing organs damaged by neighbors and other opressors from those neighbors and opressors or like substatutes but not to perform at the expense of my weaker relatives. This is not often what is chosen by families with similar means but we both dont see any benifit to doing that, as such a level of performance cant be maintained and we have plenty to spread around at a more honest level, and its a ticket to hellfire to kill people just so you can make more money when they never had an oportunity to have a personal value, or never had freedom of thought*
