I moved to Germany for the fun of it (you could say that I was seeking a better life, I guess.)
I’ve also moved across states in the U.S. for the fun it.
It can happen.
I’m aware that a whole lot of people do it for different reasons, though.
And yeah, I find it funny when Americans complain about migrants from, say, Central America. They should learn the role the U.S. played in destabilizing the region in the 80s.
