I ran across this CPI CALCULATOR
on the Internet.
Enter a dollar amount for any year, and see what it's worth in any other year. I chose to enter $50 in 1967 (my first real job) to find out how much money I would need in 2016 to buy that same amount of goods: $50 = $361. Prices have gone up by a factor of 7.
OK, well La Dee Da. What really matters is does your income keep up with inflation? In 1967, the top pay scale for "my first real job" was around $10,000. Today, as near as I can approximate, the top pay for that same job is $63,000. Pay has gone up by a factor of 6.
Salary increased 6 times.
Inflation increased 7 times.
Keep in mind that my figures are from memory and sources which may not be up to date. Also, that particular job is not representative of all jobs. Some careers may have gained purchasing power, and some my have lost purchasing power. My guess is that most have lost, but I don't know that for sure.
Also, people change careers, often to better paying jobs, so if you can remember what you made when you started working, and you know what you make today, you can see how you personally did against inflation.
What this doesn't tell us, and I think would be even more interesting, is how the average middle class wage has held up to inflation over the years. My intuition tells me, not good.
