it took Rome longer to fall than the USA has been around
I can pinpoint the day of our fall: it is when the income tax amendment was passed. From that day forward the government had the authority to take 100% of the goods. There was no limit placed on it. It's been a long bumpy ride ride on the way to 100% but unless it is limited someday by a counter amendment ( like perhaps a balanced budget amendment) this country too will come to an end.
