While it may sound cruel cutting off or weaning off these nartions that can’t feed themselves is actually a mercy.One must also stop them from coming to developed nations.
The reason its a mercy is because the more you send them, the more children they have and they become even less self sufficient. In other words the problem simply gets larger with each generation.
What is worse, they WILL NOT assimilate and they bring their failed social/’religious’ ideas with them to their host country.
They recreate, in their new home, a situation identical to what they just left...THEN they wonder why they remain poor and marginal.
