Numbers from the US are different than for here in Canada. I pumped gas for 45 cents an imperial gallon in 1970. Now it's around $1.25/litre, or $5.63/gallon. (That's around C$4.70 USG, or US$3.50). Way more than ten times here. Minimum wage was $1.25, now it's $15 in most places; 12 times more. Houses here in Canada are fearsomely expensive in the cities; a $204,000 house would be a real bargain. Or a dump. The 172 I learned most of my flying in was $19/hour in 1973; now that exact same airplane would go for $175 and a six-year-old one, which is what that airplane was when I flew it, would cost closer to $200. The instructor was $5/hour in 1973, and now he's $55 or more. Taxes hurt. Income and sales taxes are higher than they were 50 years ago, leaving less for stuff like flying. Even so, the flood of imported goods mean we can own a lot of stuff that we couldn't afford back then. A lot of homebuilders then were using hand tools to build an airplane; now they can own considerable machinery, and nice stuff at that. Some of the wood suppliers back then offered cutting services, ripping spruce to widths and thicknesses required by the buyer. A tablesaw was a luxury for some, see?
