I understand and feel your anger. However, I don't feel that what the authors are doing here is any different to what the elder generations (not just the Baby Boomers) have been doing for years. The elder generations will always see problems in the world as the younger generation's fault.
I think it's extremely noble of you to help your children with their university fees. My parents could afford to (and I had my student loan means-tested because of that) help me out, but they chose not to. Both of them earn a rather high wage individually. Unfortunately for me, they never even offered to help me out. They were going on round the world cruises and days at the races (the kind of events where you spend a month's wages on a suit before you even start gambling). My father is less selfish than my mother, I have to say.
Surely, as a loving parent of not one but two children (I'm an only child, by the way), you can surely see that to gamble away money at the races while your only child loses sleep and can't afford to buy a winter coat and boots to keep the cold out or nourishing food to eat (such as porridge, potatoes etc.) because all the money from the student loan pays their exorbitant rent is pure selfishness.
When I finally did graduate (with an Upper Second Degree in English), my parents did allow me to live in their house once again, but they treated me as nothing but an inconvenience. When I said that I would rather try and get a paid job working as a receptionist in Wakefield Cathedral, I was instead bullied into taking an unpaid internship by my parents (they have, all my life been emotionally and at time physically abusive). It was only when my future husband brought me to live with him instead (yes, in a poky over-priced flat, not a house) that I stopped actually feeling suicidal.
You are a very self-less gent. I think it's extremely generous of you to prioritise your children's education and leave them an inheritance. I understand that you feel hard done by that you are unable to retire and enjoy freedom before you do get old. Still, not everyone is like you. Most of the Baby Boomers I speak to seem to think that those under the age of about thirty should be committing mass suicide and giving all the experienced mature generation a break. You say (with irony, obviously) " Sorry if I don't die early enough." Well, I'm sorry if I was born and am preventing the elder generations from retiring.
One other thing, you mention benefit levels. If like me you have only worked for no money (and working for no money doesn't mean you work any less hard) in internships and volunteering for charities, you aren't allowed to claim any benefits (not even job-seekers) because you've never made N.I contributions. That's what I got for working for free, condescending attitudes from the people at the job centre and no help from them either practically or financially. If my future husband wasn't looking after me, I would be homeless.
I hope I have not offended you, but it can't be that far from the truth that for every young, bratty person living a "comfortable i-Life" there are countless more who are unloved and unsupported by their parents, working indefinitely in an unpaid job, having to swallow anti-depressants and contemplating suicide.
When we get our careers, we will pay our way and your pensions as well. We'll make it up to you. Unfortunately, I can't imagine that happening any time soon.
