Common European culture is enabled by dirt-cheap Ryanair and easyJet tickets(Berlin-Milan is 30 EUR round-trip) and open borders. Just hop on and explore your neighbour's thousand year old history.
Many Europeans have studied, worked or otherwise lived abroad, not to mention all of those who benefited from those dirt cheap flights.
It's quite amazing that you can drive from one end of the EU to the other without showing your passport, learning new road signs, exchanging currency (with some exceptions), getting a new SIM card, or waiting at a border crossing. If you live in Berlin, driving to Warsaw is no more of an inconvenience than driving to Frankfurt.
I don't know what we get out of the U.S. border situation. People who have to commute between the countries hate it. People who work these posts probably hate it. Trucking industries hate it. Tourists hate it. And yet, based on what I see in my city, the cartel has no issues getting drugs in for cheap enough that someone with no income can be high for every waking hour of their life. I just want to be able to go to Tijuana without the traffic jam. I didn't ask for this damn wall (well, sturdy fence, really).
That's what happens when elected representatives from Wyoming and Tennessee have a congressional majority over the control of a border 1,500 miles away from them.
Stoke fear of immigrants to get yourself elected, then make legal immigration impossible so that illegal immigration is the only option.
