At the same time, however, one didn't have to make the equivalent of today's high mid-six or low-seven figure salaries in order to be able to afford to purchase a home in a world-class metro area. Today one needs to make "world class" money in order to afford to purchase a home in a world class city, due to the perfect storm of NIMBYism restricting supply and a high amount of demand from a large pool of well-heeled buyers. I don't want to come off as whiny, but my salary is only in the low six-figures and my company doesn't provide RSUs, which means I'll never be able to buy a home in Silicon Valley, short of winning either a state lottery or the "startup lottery." Yes, I can relocate and purchase in a cheaper locale, which is something I'm strongly considering once I get married, but that comes with major career tradeoffs; I'm a specialist and it may be hard to find jobs in my specialty outside Silicon Valley. There's also no guarantee that these jobs will be available remotely, especially with the pushback against remote work.
I'll share a family story. My grandfather was born in Arkansas during the height of Jim Crow. He never went to school, and he never learned to read or write. He and his family moved to Bakersfield, CA in the 1950s as part of the Second Great Migration of African-Americans from the South, looking for better opportunities and to escape Jim Crow. He worked on a farm for over 30 years. Despite these challenges, he was able to purchase a modest home there, and he managed to pay off most of his mortgage debt before he was forced to retire. This would be very difficult for a farm worker today.
I have other grandparents who still faced racism but were literate, and they were able to purchase homes in places like San Luis Obispo County back in the 1960s. Now, I wouldn't want to trade places with my grandparents; I'm glad that I was born after the Civil Rights Movement. I'm fortunate to have many opportunities that my grandparents and my parents didn't have. But today's housing prices are one of the most formidable challenges facing my generation. It seems that opportunity in America (and around the world) is increasingly being concentrated in a handful of "winner" cities, and the demand to live in these cities, combined with a reluctance or even unwillingness to grow to meet the demand, has caused housing prices to skyrocket. But moving outside these cities means running the risk of having few opportunities; witness the chronically higher-than-average unemployment rate of the Central Valley of California, and witness the Rust Belt.
