Add a glass wall so the Americans can see what they're missing?

This is in VT, so people there already know what they are missing. In fact, it use to be in border communities with Canada (at least in NE), crossing the border was like walking across the street.

Trump wants to destroy that and it seems to be working. People in the US needs to raise up and end this MAGA trend fast.

Passports were much rarer before WW1, it is indeed a bit bizarre as the world allegedly embraced liberalism and moved away from imperialism that the real crack down treating humans as property of government that need hall passes and permission slips really went into gear.

This may be the byproduct of more robust social benefits, it requires brutal totalitarian control of immigration to smite the 90% of earth that would be better off in North America.

No need to bring WWI into it. Back in the 1980s we visited Canada on a family road trip. My Dad showed his license. That was it.

In 1991 I drove from Buffalo to Detroit along the QEW in Canada. Only had a license.

In 1993 I walked from El Paso into Mexico, then walked back. All I had with me was my license. Didn't need to show any id to enter Mexico.

That's all after the decline of robust social benefits which the US had in the 1950s-1970s.

You still don't need ID to enter Mexico 9 of 10 times. The only crossing that even glanced my ID was Tijuana. Of course it's not like they have anything to lose, if you don't have money or work they're happy to let you perish in a ditch, and the cartels aren't going to let you compete in crime.
