I disagree. In fact, the opposite could be true. The focus on material possessions like clothes, diamonds, cars, homes, and just in general -- consumption -- has made us less healthy than we otherwise would be and we don't have money to spend on good food, the time to exercise or find peace of mind.
Just because we got bigger houses and less polio in the same timeline doesn't mean those too things are correlated to the same cause. In my experience, most of the scientific researchers producing cures for disease and prolonging life aren't doing it for material wealth. There's a deeper drive to it than that.
Maybe the progress in healthcare proceeds against the tide of social forces. It probably does, considering doctors artificially limit the supply of doctors, precisely so they can buy bigger houses, fancier cars, and more jewelry.
It's estimated that Jonas Salk would have made $7 Billion if he'd patented the polio vaccine.
I believe if we are going to reverse the damage we have done to the planet, we have to invert our social reward structure. We should shame those who spend extravagantly and praise restraint.
