John F. Kennedy's insight about democracy and walls

John F. Kennedy said this in a speech he gave in 1963:

Freedom has many difficulties and democracy is not perfect, but we have never had to put a wall up to keep our people in, to prevent them from leaving us.

This is extraordinarily insightful!

Indeed, consider that all countries have borders, walls (figurative, sometimes even literal walls and fences).

During the recent history of humanity in some countries those walls have existed to keep people from entering illegally. In other countries those walls have existed primarily to stop people from leaving illegally.

Consider which kind of countries have walls to keep people out, and which kind of countries have walls to keep people in, to stop them from escaping.

Now consider that the far left is precisely advocating for the latter type of governments, to replace the former type. They want a government that has historically (and even to this day) built walls precisely to keep people from leaving.
