In 1970 an ounce of gold was $35, so that means to have the same purchasing power (in terms of gold) in 1970 you would need $5,180, and given the minimum wage of $1.60 per hour at the time, that means you would need to work 3,238 hours so assuming a regular 8 hour workday that's 405 days so assuming a 5 day work week working 48 weeks per year that comes out to ~1.7 years. So that means a random boomer working a minimum wage job in 1970 (that he got with a high school diploma and a firm handshake) was earning the equivalent of about $353,000/year.

To make that boomer minimum wage of $353k/year would require he earn about $184 per hour. In 1970 a salary of $9,870.00 was considered to be pretty good, and given the price of gold at $35/oz, that comes out to a salary of 282 ounces of gold ($1,143,510.00) per annum.
