There are few things more depressing than people who have gone through hard times, are now well off and yet have absolutely no empathy for people who are in the position they once were.
Do people like this not understand the concept of luck? You had hard times, suffered etc but ultimately YOU WERE LUCKY! You weren't struck down with a disability that made working impossible. You may have worked hard to get good qualifications, but first you had to be lucky enough to access a course and to be able to finance it, perhaps with free tuition fees and student grants that no longer exist. Not to mention lucky enough to have the degree of intelligence needed to succeed in your studies.
You may have a high powered, well paid job now, but that is because you were lucky enough to see the advert at the right time and get to the interview. Lucky enough to have the characteristics valued by your company that put you in line for promotion. How many equally or more deserving people didn't see the advert because they had flu that week, or didn't apply because they would never be able to afford the commuting costs? Were passed over for promotion because they had a chronic illness or caring responsibilities which meant they were perceived as less able?
The fact is, however hard you have worked, however many hours you've worked and however many sacrifices you have made, there is a massive element of pure chance in your success, for which you can claim no credit whatsoever. Other people don't get these chances and so are not wealthy and secure, regardless of how clever, hardworking or ambitious they are.
So a little bit of humility and gratitude is in order, please.
PS It's also fine not to support other people's children if you have none, assuming you will be getting euthanised the day after retirement, so as not to benefit from any of the services those children's taxes will be providing for you...
