The assumption that impact of military life on a married servicemember is more significant than that for a single one is stunted thinking, indeed. There are plenty of things a single guy could be into that are severely impacted by military service. The service shouldn't concern itself with any of them. They're personal choices and should be dealt with personally by the member.
I was on single BAH for more than half my career, but it was about even between single/dependent BAH over the period of my CMR time, so I don't think bias has anything to do with it. Quite the opposite in fact. I'm able to look at a situation and come to a logical conclusion even if it's bad for me personally (doesn't impact me at all anymore, except as a taxpayer, but I would have said the same when I was collecting dependent BAH).
Got dat pair of panties.
Of course not. Once you hand out an entitlement, you can never take it back. The uproar would be tremendous. This forum certainly seems to know that...just selectively when it impacts others and not themselves.
