History is consistent in one important way. Empires always fall, and there are three main causes for the collapse. Succession crises, corruption and debt are what eventually bring them down. And the cause of debt is always an insatiable appetite for war – either from a need to defend the borders or expand them.
In the US today, there is no concern about succession, as our Founding Fathers made sure that wasn’t an issue. Corruption is certainly an issue, but it’s nowhere near Roman levels at this time. Debt, on the other hand is mounting rapidly.
What is the cause of that debt? Despite many deflections, it’s not caused by taking care of people. Our debt can be directly traced to our appetite for war.
