Well romanticising your poor student days compared to today's supposedly wealthy students is how it came across, whether or not you intended it.
You said you were poor and had no money left after food and had to shop at charity shops, whereas students today are eating out and shopping in the city.
In reality there have of course always been students attending night clubs in the city. Back when I was at uni 15-20 years ago, some students would spend all their money on booze and have none left for food. Others would have plenty of money for nights out. There's always been a disparity.
But overall, today's students are much worse off, and anyone saying otherwise is deluded.
In your post there was an implication there that students today have it easy and you went through some kind of lack of wealth that they'll never understand.
That's simply not true. As a whole, young people today are much worse off, and their future prospects, both economically and considering climate impact, are shaky at best.
Just because you sometimes see them out in the city doesn't negate that. This has always been the case and students find ways of having fun.
