I will give you another. Gas prices have kept pace with wages. 1972. When I started driving, gas was the equivalent of .08/litre. Now it's 1.03/litre. That is an increase of 1300%. When gas was .08/litre, I was earning $.90/hr. Minimum wage. Minimum wage is now $11.25 close to 1300%. But in January, the minimum wage will be $14/hr. Close to 1700%.
Hamburger has gone from .49/lb in 1972 to 2.50/lb. A 500% increase. That's better than gas.
We would have to examine incomes at a given point in time and all the expenses you would have had then. We would have to repeat the exercise for right now. It would be case by case.
You can go ahead and waste you’re time.
Both my parents purchased their homes in the 1990’s on their single incomes. while smoking cigarettes by the carton and active social lives every weekend.
Today people don’t smoke, drink, or go out and they barely pay their bills with two incomes.
