I agree with you - fully realising that by 'these types', you clearly aren't referring to all older people in any way.
It just seems so counterintuitive to want your children and grandchildren - not just younger generations in general, but your own family - to struggle more than you did, just so you can maintain the narrative of yourself as the put-upon martyr and them as the spoiled 'don't know that that they're born' lot.
Yes, different generations face different challenges and opportunities - although by no means everybody in that generation - but you have to accept that you live when you live and you have to take it as a package.
My DS is 13 and is already concerned about how he will pay for university. I didn't have any tuition fees to pay at all, and I even got a bit of a grant at one stage. I'm terribly disappointed on his behalf; of course we will do whatever we can to help him, but we aren't lording it over him with tales of how much harder life in general was for us and how much luckier he supposedly is.
In 40 years' time, he will likely be living in great health, prosperity and enjoyment; whereas I will be long dead. I'm genuinely thrilled at the prospect of how great a life he can hopefully have far ahead of him; I'm not making it all about me and bemoaning all the negative things that have befallen me, whilst conveniently glossing over all of the positive things in my own lifetime.
