Whose ownership? Part - II

Like a problem called as "Illegal Immigrants"
Where does this illegal word came from, who declared them as illegal, who got the ownership of declaring them as illegal and who has drawn the boundry.
If they had survival means, why will they be leaving their homeland?
So a Bangladeshi can not work in India but a Nepali can because India has treaty with Nepal. Similarly analogy will be of US, Canada and Mexico.
So poor Nepali's have right to come and work in India but Bangladeshi's don’t have it.

Whose ownership?

Logically when life started on earth everybody had equal rights of ownership but over the time some small number of people became owner of this world. So a person with lesser power (often called as poor) his/her "illegal" dwellings will be demolished but powerful people (often called as rich) will regularize their commercial (read illegal) establishments for benefit of economy.
