Is a in country enforcement necessary in Nordic countries
In Nordic counties the idea against illegal immigrants was to make themselves want to leave. As in they can’t have a job buy a house or even groceries online.
So illegal immigrants worked in underground groups.
But the Nordic countries made their counties nearly cashless. Since they can not get credit cards or a national number they can not bypass this
But they can trade for goods.
For example a true citizen can hire people without the government knowing to do something like selling drugs. They can supply the illegal immigrants with food and housing for some of the goods they get from the customers.
Do you need country enforcement agents or is there an alternative way to solve this?
