They said at this point they expected to have more, and they were feeling down about how little you get for your money these days.
To take the first point, not everyone’s expectations are the same. They will depend on all sorts of things, including age, qualifications, experience, location… A 20 year qualified actuary in London will have different expectations to a not long out of school teaching assistant in Leeds. That isn’t a judgment on anyone, it is just reality. What we expect to be able to earn, and from that, the sort of life we expect to be able to lead is massively determined by all of those factors (and more). You can’t say whether the OP is being reasonable or unreasonable without knowing the detail on that.
On the second part - we can all see that we are not getting as much for our money anymore. From people at the lowest income level, to people earning hundreds of thousands, everyone is thinking WTF - my money is not going as far as I feel like it should.
Yes that absolutely hits people on low income the hardest, but for people on higher incomes who were chasing a life they wanted to lead, they are also feeling a bit screwed, and might be questioning whether the investment in time, education, effort etc was all worthy, because it doesn’t seem to be paying off in the way they imagined.
That feeling is deflating. People are feeling they were sold a dream that doesn’t exist, or at least - is pulling out of sight faster than they can chase it. I can sympathise with that feeling.
