If there are no borders, then there are no individual countries either. Hence there is no place to seek refugee at if the one country that exists is turned into a dictatorship.
That refugees move from one country to another is not an argument for a borderless world. You are taken my argument that people should be able to move between countries to a logical extreme by suggesting they should be able to move without restriction which is what open borders entail.
We don't have open borders today, yet we allow refugees. With no borders you couldn't even be a refugee because there would be nothing to escape from. You could end up with tyrrany everywhere.
Of course borders work, and it is a sustainable solution. It has worked for thousands of years.
Doesn't matter how irresistable a country becomes to anybody not born there. Relatively few mange to get in when borders are closed. The US is an outlier given its enormous border to Mexico.
Secondly the US is an outlier by having the braindead policy of giving citizenship to anybody born in the US, even if they arrived there illegally. That is a profoundly powerful incentive for people to sneak into the US.
The second problem in the US, is that illegals is basically something quietly wanted in the US. It provides businesses with dirt cheap slave labour. Employees who can never complain or risk deporation. If they really cared about illegals in the US, they would have cracked down on the companies that employ illegals, but they don't because they know it is bad for business.
They are against amnesty because it would give the workers rights, and ability to bargain for better wages.
The sensible approach in my view in the US would have been:
1. Stop giving citizenship to people born in the country.
2. Strengthen trade unions. These are good at policing companies employing illegals for crap wages.
3. Give occasional amnesty to illegals, otherwise a large population of illegals keep growing. Outside of amnesty periods however, you got to deport people.
Letting some people in as workers with skills is fine. Giving amnesty on occasion to illegals if fine. Letting in asylum seekers is fine. But a free for all, anybody can come whenever they like is a economic and political suicide for any state.
