Thats what we do now though with the Fed and inflation.>>825089
I appreciate that and im sorry for my wording earlier.
I dont know where you got those numbers but if we accept them as true then the three sources of revenue for the war are basically less than 10 percent foreign loans and the rest basically is bonds sold which were purchased by wealth accumulated from agriculture at least half of which was accumulated by slave labor and freshly printed currency backed by future domestic production of course earned through slave labor.
Additionally the colonists only held their land, structures, gold, shops, crops et al through the British military resources which were expended winning the "french and indian war" as we call it in the us, called the "seven years war" everywhere else. That war was won with the proceeds from slave labor as well as the loans taken by the british empire against future production by slave labor. If not for that war effort, the military might of the other European powers would have presented a threat that would have prevented Revolution, and if not for that war debt the Empire would not have levied the modest administrative taxes in the Colonies that were exagerated to foment the backing among the colonists that was needed to create the support needed to have a Revolution.
Basically, the fruits of slave labor.
Which reminds me, the true support for Revolution was propaganda. The printing press and propaganda exagerating the reality misnomered the Boston Massacre and the severity of the Stamp Act etc was the true power behind the purchase of those war bonds and the volunteers for the Continental army.
To answer the OP, the single greatest factor is actually, and always has been, fake news.
