Tell me a place in any Western society (outside of run-down rural areas/flyover states) where an average employee (i.e. no ultra-rich tech hipster bros) is able to afford a home before the age of 30 purely by his own savings and income. That is frankly no longer a reality for most people.

It is perfectly doable, even common, to buy a home in low and medium COL areas without any assistance from family, living or dead. The fact that you can't do this in NYC or SF is not an indictment of anything other than NYC and SF.

But there aren't any jobs there, so you're going to need an inheritance to support your family of 5.
