What good or service do you believe the median male has less of today than he had in 1968?

If your claim is correct, it shouldn't be hard to answer this question.

Job security, and a defined-benefit pension. That's worth a lot.

Would you drive a 1950's car, live in a house half the normal size, and give up all medical treatments invented since 1950 to get those things?

Back in the 1950's you has cars much less reliable than today, but you did not have bedroom communities two hours away from your workplace. You had smaller houses without air conditioning, but you also had smaller energy bills.

What I'm saying is that the technological advances have a way of changing the playing field, in such a way that they gains are much smaller than one would have thought.

Homemaking services.
