We need a time machine.
McDonald's Menu - 1972
At the time, minimum wage was $1.60. Still want to go back?
It's all relative. Anything from 1972 would sound cheap today. For example, in 1972 you could buy a brand new Datsun 1200 for $1600, or a new 510 for $2000. You can't buy a rusty shitbox 510 for $2000 now...
