At the same time complaining that they couldnt afford to buy a house and how all of us older generation sold them out
They sound like spoiled brats but they aren't wrong about that bit.
My children are in college and they travel and I did a trade and didn't go to college. I worked in excess of 60 hours a week for nearly 2 decades. I cycled into work when my first child was born because we couldn't afford 2 cars. I often worked 16-18 hour days. Sometimes I worked through the night and through the next day (in excess of 36 hours without more than a 30 minite break in a factory running machines)I didn't take holidays for years etc etc, blah blah blah... that doesn't mean that my generation and, more particularly my parents generation, didn't sell them out. If you want proof look at how wealth distribution by age has changed in this country over the last 30 years.
Two things can be true at the same time.
My college going children all work as well so between work, college and study they are doing in excess of 60 hours a week. They work just as hard as I worked. In fact it's true to say that they've worked hard all their lives.
I bought my first apartment when I was 22. They'll be in their 30's.
I've a large amount of unearned wealth in the form of property price appreciation and pension value appreciation. They'll probably never have that, until they inherit it in their 60's or 70's long after they actually need it.
I can retire at 66 with a very generous State pension. I'll get massively subsidised State healthcare and massively subsidised private healthcare (subsidised by younger people who are also insured). They probably won't have that.
I could have a family in my 20's and 30's. They'll probably be in their 30's or 40's.
They got to grow up with the internet, cheap travel, hundreds of TV channels, in a liberal country free of the oppression of religion. They can expect to live into their 90's so they get plenty of positives I didn't get... but they may never own a house.
