Its not so much that relative prices have gone up, its that dollars buy so much less. Inflation and all that debt the government prints money to pay the interest on have an impact. There is something called the rule of 72. Divide an interest rate or inflation rate into 72, that tells you how many years it will take for money in dollar terms to double. At 2%, 36 years. At 4%, 18 years.
In 1971 I got out of the army and got a job as an underwriter trainee at $8,000 a year. I bought a Dodge Dart for $2,000. Rent for a 2 bedroom apartment downtown about 6 blocks from where I worked was $135 a month, plus $7 for a parking place. Dicks Drive In sold hamburgers for 19 cents, and Thriftway sold steak for about a dollar a pound. And of course Gold was $35 an ounce (troy ounce, somewhat different than normal ones.) This was in Seattle, where the Boeing depression was in effect, they went from somewhere over 100,000 employees to about 40,000. There was a billboard, "Will the last person to leave Seattle turn out the lights." So rents might have been depressed compared to other cities.
Cars cost more now than what houses went for then. Gold is north of $1,000 an ounce, last time I looked. Dicks sells hamburgers for $1.40. There is agitation, successful in some places around here, to raise the minimum wage to $15 an hour. For a 2,000 hour years (50 weeks at 40 hours a week) that is $30,000 a year. People especially families may have difficulty living on that wage, certainly if they want to live downtown.
