I am going to continue with something that Ms. Chow said at the end of her remarks.
The concept of citizenship was developed in the 19th century for the most part, at a time when people travelled far less and citizenship implied fewer things. There were no social programs, nor was there a welfare state. Basically, citizenship boiled down to a title and a passport, in a way.
We can see the limits of this concept. Is a person's birthplace still relevant to assess citizenship? Some people are obviously connected to a particular country, but do not have citizenship, whereas others have no connection to the country that they have become a citizen of.
Should we not take another look at citizenship through the lens of the 21st century and establish true criteria for assessing a person's connection to the country, rather than using arbitrary criteria such as place of birth?
