"they just bang on and on all the time about the fact that they have pay FULL council tax, bus fares, yada yada yada."
I think you may be thinking of particular individuals, not all baby boomers
"And if it wasn't for them, we'd all be speaking German ya know!"
As tethersend has already pointed out, the baby boomers were born post-war, so whoever you have in mind here, they are not baby boomers.
"And even worse are the ones who sell up, go to spain and piss every penny up on cheap booze, leaving the kids nothing."
As a working-class baby-boomer (tail end of) I grew up in a world where inheriting happened only in the upper classes. You came into this world with nothing and you leave the same way. And isn't the person expecting/anticipating an inheritance the one who is being selfish, expecting to receive something they have not earned?
That said, I will agree that in some aspects, baby-boomers had some things easy - but some things harder. Sex discrimination was still quite overt when i started work, equal pay was a law which was paid lip service only. Rape happened because you 'were asking for it' and wife-beating was still a dirty secret.
Plus, for the future - we are the generation who will be looking after our elderly parents whilst still supporting our children - we are morphing into what I believe is called 'the sandwich generation' because of this, sandwiched between the two generations we must support.
