FFS! Why did you take that "you've changed" comment seriously?
Some rich and wealthy will usually fight when they believe the fight is worthwhile but they don't need to enter battle to do something worthwhile. They can provide money, supplies, arms, housing, places to provide medical care and other things.
How would the poor afford the increased taxes and expenses imposed by the Crown?
Some of the original funding of the colonies originally came from the Crown- they had 'governors' who managed them, the colonists were required to do their share and if they didn't, were sent off. That lasted for awhile, but in the second half of the 1700s, when Britain was fighting some wars that had nothing to do with America, the colonies were taxed more heavily as a way to add to the war fund- read what the Founding Fathers had to say about that.
I haven't seen much that supports your ideas about the minority supporting the Russian Revolution and the Wiki link shows otherwise.

The American colonists weren't sent to vanquish the native people and weren't part of the British military.
WRT East/West Germany, you're referring to them being called 'East Germany after the Berlin Wall was erected? Germany was forced to accept blame and pay for reconstruction as terms of surrender but most of Europe hated the Jews, so why is it a surprise that East Germany "washed their hands of it"?
