Lewis L. Strauss
Speech to the National Association of Science Writers, New York City, September 16th, 1954
[New York Times, September 17, 1954]
Assuming he's talking here about the Baby Boomers:
1: Meterless power
Not as such. I don't offhand know how our energy costs compare to the 1950s.
2: Famines eliminated
The rate of death by starvation has declined and regions that once had periodic famines have not had them since Strauss made his commnets (India in particular and it suffered a major famine not too long before Strauss made this statement). We still have famine, though.
3: Effortless and safe sea and air travel
I'd put our safety standards up against those of the 1950s any day but alas, security theatre is adding some needless tedium and difficulty to the process of getting from A to B.
4: Increased lifespan
Maximum lifespan is stalled at around 120 years but life expectancy continues to rise, although not for all groups and not dramatically (at least for most groups) over short periods of time. Americans, for example, had a life expectancy of about 68 years in 1950 and they have one of about 78 years now. It's not unreasonable to think that by the time the last Baby Boomer breathes her last, lifespans for Americans will be north of 90 years, significantly longer than in 1950.
