I agree with you upto a degree Oldun.
The IHT only used to affect the very wealthy but now it affects (or will affect) almost everyone.
I was born into poverty (by todays standards) in a tiny 1 bed flat on the banks of the Thames with no bathroom and only an outside loo.
I am where I am through luck and hard work, so yes I am a lot better off than my ancestors but I think the main difference between now and then is firstly education and secondly a healthy scepticism of political motivation.
I have no doublt that my grandparents would be proud to be bashed over the head by Tony Blair or the Queen, and would accept it without question. I wouldn't, and I do.
