What evidence is there ? 1 prince does some military service in Afghanistan where chances of death are evidently low 150,000 troops are rumoured to have served there, only 547 died, those odds are probably better than odds of being involved in a car accident in the UK, so does that now mean that in reference to my original point, that the poor don't mostly serve on the frontline because a single prince did it in a relatively safe war ? 547 die in a single morning in Ukraine, not exactly an equivalent is it where that amount died in over a decade. In an actual war like in Ukraine with people dying en mass it is always going to be disproportionate for poor people doing the dying because that's the simple reality of war and life, so I'm not sure what is surprising that the poor from Russia are dying en mass ?
I think you're generally correct in that most of the time it's lads from working class backgrounds and poorer people who do the fighting, how ever the Royal Family have basically served in most of wars the UK has had, Prince Andrew obviously in the Falklands, both William and Harry in Afghanistan. I think you can just concede that the Royal Family have actually fought in wars, but most of the time it's poor people.
