Indeed becoming a property owner became much complicated today than 30-50 years ago. However, youth generation also became different and I dont think that many dream of having their own flat or house. It past people were ready to work on same work and live in same town, house or flat forever. Now youth generation prefer traveling, changing jobs frequently, be free and independent. Now they have to many option to change, to many things to try or to have, and having a real estate will bind them to one place.
Now it's time for having wholesale changes and it's working because sometime back having own house and car was social Simbel for many around the world but now it's completely changes peoples love to live on rent and want to keep their money in use which is more profitable.
In many cases technology related peoples also not want to live on one place as it can't be good for them so they always want to keep moving which is more adorable for them so they never think about having own home staying and moving is more profitable instead of living on one place. But in few countries still things are not as working in developed because peoples still bounded with their culture and want to live as they were living with their forefathers but near future is heading for many big changes.
