The Saturn V, in 1967, was expected to boost 115 tons to low Earth orbit (LEO) for $540 per pound (1967 dollars) and it was the cheapest per-pound launch vehicle there was.
Guess who is doing better than $3,825 per pound to orbit? SpaceX, that's who. Right now they're running about $2,115 per pound to LEO. Falcon Heavy is expected to cost--get this--$772 per pound to LEO.
Damn I loves me some SpaceX! Those guys are awesome!
