It's still possibly to own a home if you prioritize and budget. It's about priorities. Mortgages can be less expensive than rent, too.
I don't want to hear about income and generations. I started saving for my first house when I was earning @ $10 thou a year. The average salary at that time for a college educated person was $30 thou/yr and this was during the housing bubble in one of the priciest markets in the country. It took me eight years to save. I bought my house at age 29.
For some people, particularly extroverts, spending on experiences is more important than spending on a space to call one's own. That is a valid choice.
To do away with the concept of owning homes we will need a huge shift in consumerism and capitalism. As a whole, we will need to buy less because we'll have smaller spaces and we won't have "permanent" spaces. This will cause a big shift in the economy, industry, and politics. That is one reason why the concept of owning a home will endure. In general, though, the concept of renting could be better for consumers, not to mention better for the environment, so there is push and pull of who/what will benefit from the shift.
