I think the current generation (born 1960s onwards) have on average much easier more luxurious lives than those who came before.
I may not own a house but I have plenty of clothes, food, access to a university education, have enjoyed a foreign holiday most years, can eat oranges and bananas all year round.
Many of the "boomer" generation may be well off now but childhood in those days, growing up in the 40s and 50s, was much harder, there was grinding poverty in many places, mental health issues among parents, all the loss and devastation of the wars. Many of the women and working class people had no chance at higher education and went into menial low paid or hazardous roles. Indoor bathrooms, central heating, washing machines were all luxuries then. Nowadays even the poor have those things.
It's also true that house prices in many parts of the country are affordable even for people on low incomes. There's always the option of moving to a cheaper area if buying a house is really that important to you. Saving the required deposit of say £10,000 is very much doable by forgoing a few expensive luxuries for 2 or 3 years, if you live in a shared house in say Liverpool, even in a relatively low paid role. More difficult if you have children already but that was always the case.
Many people just have no idea how lucky they are
