Perhaps we'd all be less inclined to pity our own generation if we looked back a little further than the one or two before us.
Having heard from elderly relatives about living through (and fighting in) the world wars, about the reality of high infant mortality and far less developed medicine, about the lack of help for the poor, some of whom were literally starving, should we be complaining?
I don't like my student debt, but my grandmother couldn't even accept her grammar school scholarship at 14 because her mother couldn't afford the uniform. So she had to get a job instead.
I don't like that I'm poorer than most baby boomers I know, but I live in an age of the welfare state and free healthcare, unlike my great grandparents, who didn't even get free healthcare for problems related to injuries sustained fighting in WW1.
And that's before we even start considering the billions who are poorer than us, and live harder lives, and will die earlier. If birth were a lottery, we've come out with some major prizes.
