America has been in decline since the 50's. The 1850's that is. We've had a couple of shining moments in the sun in the last century and a half, but for the most part it's been all downhill because we have abandoned the basic principles, morals and values that this country was founded on. Unless we return to those things this country will continue to decline until we cease to exist, probably within the next half century.
You can never go home again, Anachromism.
Not unless you're a time lord, at least.
