When Kennedy was shot, the minimum wage was $1.25 an hour. Gold was $35.25 / ounce. Today, gold is $2,640.00. On that basis, if the minimum wage was in real value equivalent to what it was when Kennedy was shot, it would be (rounded down) $93.61 / hour. (That's around $190,000 a year. That sounds like a livable wage to me).
The median income was $6200 in 1963. https://www.census.gov/library/publications/1964/demo/p60-043.html
For a 2000-hour year, that comes out to $3.10/hr
Minimum wage was therefore roughly 40% of median income. I guess that may be a livable income.
In 2023, it was $80,610. https://www.census.gov/library/publications/2024/demo/p60-282.html
To keep up with the median, minimum wage would be $16.25, which is near the high end of minimum wages by state, and significantly higher than the federal minimum of $7.25.
The use of gold as a standard is highly misleading, since we are not on the gold standard anymore. Otherwise, the median income should be around $475,000.
