Decline of the Roman Empire (Decay Theory)

I agree with what the Wikipedia article, "Decline of the Roman Empire" claimed to be the cause for the decline of the Roman Empire. I agree with the idea of how the Roman Empire collapsed because of the loss of civic virtues. People were not self-sustaining and relied on barbaric mercenaries who ended up turning on them. In addition to the military decline, I concur with the article that the Roman Empire had collapsed because of the development of a nonprofitable economic system, where the Roman Empire had a market economy that and a free trade policy; flaws like this are reusable causes for inflation. In addition to this, I also agree that the many occurrences of civil wars between decided parts of the Roman army, fighting for control over the empire. What once was a strong military force, and weather it had barbarians or not, was weakened by the decline in economic status. In total, I believe the factors that the Wikipedia article gave for the decline of the Roman Empire where quite accurate and evidently possible.
