Just wait until they grow up in a decade (yes. they’ll take longer) and have a baby and seriously engage in marriage. they will start thinking . . . hmmmm. maybe a house (or a condo) makes some sense.
How will a house make sense? The median price of a house in San Francisco is now several times what the projected LIFETIME earnings for a high school graduate was projected to be in 1962, the year I finished high school. Bear in mind that studies now say that a current bachelor degree is worth considerably LESS in real terms in the labor market than a high school diploma was worth in the sixties. Just to rent a home in San Francisco costs what used to be a high level executive salary in my youth.
For perspective let me add that I spent almost a year on the old Navy training base on Treasure Island in San Francisco bay in 1962 and 1963 going to electronics school. My pay then was less than one hundred dollars a MONTH, let that soak in, that is NOT a typo. On that pay I had many a good time in the city. Mixed drinks at Lefty’s were fifty cents each. A ride on the cable car was maybe a quarter, I am not sure it even cost that much. Two of my schoolmates who earned only slightly more than I did (because they had more time in grade) rented a two bedroom apartment in Frisco to have a place to party with girlfriends on the weekend. You could have lived a year in Frisco back then on what a couple of months rent would be now. At some point this absurd California real estate bubble has to burst, it is as certain as the sunrise. If drought conditions persist long term there WILL BE a massive exodus from the state. In that case houses will be available for free to snakes and scorpions.
I think the coming generations will not "seriously engage in marriage" for the most part. Why should they? Our culture has told young women that marriage is bad for them, has no societal value other than as a social contract between two people, and exists solely to put women in a position subservient to men. It has also told young men that they are unnecessary except as sperm donors and cash cows for their ex-wives, and if they do stick around to try to help raise the kids, they can expect to be treated as clueless idiots, potential abusers and rapists, and little else.
