@Guillermo ********
Man, you are a joke. I know of several people who applied with their own bank account, showing 500K+ THB, and who are unemployed. This is most probably what happened in the case of this Japanese applicant you have referred to. You are just talking BS based on some personal, ungrounded assumptions.
EDIT: The only place I have heard of which insists on regular income (even for soft power) is Taipeh.
