Are you joking? Real estate prices have skyrocketed compared to previous generations. Things have worsen a lot the past 10 years as well, while short term rentals have also affected the market. Yet, you're blaming the new generation for buying coffee instead of making it on their own as an excuse for not being able to afford a home. This is pure ignorance.
I don't know where you're from, but in the U.S. a house that costed $200,000 a decade or two ago, now may cost up to one million dollars. The same applies in many European countries as well.
It sounds a bit harsh but I agree with you, this is serious ignorance. Real estate prices have increased significantly in recent years mainly due to currency devaluation, supply-demand imbalance, high demand while real estate supply is limited. At the same time, inflation is making life more and more difficult for people, with many struggling to even afford basic daily meals. Therefore, owning a house has become a luxury, even if they save their whole life they can never own it.
This is why owning a home/property is becoming a luxury and expensive these days.
