“Affect travelers” is going to be the least of their problems. The big question is whether wholesale collapse of economies and governments is going to happen followed by massive unrest and the rise of governments antithetical to freedom. That and mass starvation and people freezing to death. Lastly, will Europe finally give up on their stupid utopian “green energy” wet dream and will the USA take lessons from their folly?
“...and will the USA take lessons from their folly?..”
Of course not.
