I'm a strict leftist, that means, i believe that humans (in fact, all life) are valuable. Yes, you have to say that in these times. Lots of politicians these days seem to disagree with even that.
As a direct consequence, i advocate for UBI (universal basic income). Because the people need to live off something, and it is getting harder by the year to be successful through your own labor. (As numerous articles describe, - i won't link them here, because that would be out of scope - hashtag "working poor").
However, i think the borders must be closed. That affects both goods and migration. If the borders are closed, people stop competing with one another. Just a reminder: "compete" comes from Latin and basically means "fight". People are fighing against one another, and i think that makes a society sick. If the borders close, economy slows down considerably, and people stop competing.
