The real reason America is in decline is because Americans nowadays are no longer interested in being American citizens but rather being American residents. They don't care what happens in the long term because they just move to wherever is economically appealing, and then proceed to leech off it. No settling down, no consideration of the future, no attempt to preserve the ways that led to prosperity.

How do you get a population to invest in a place when there's nothing being done to defend it? We're being actively invaded and the government is assisting in that process so you can't safely set down roots anywhere because they'll just direct invaders to whatever settlement you carve out for yourself. It's fucking evil.
