How are the oldest workers directing their dollars? Is it to buy more useless crap supplied by Chinese workers? Where do ERE's send their dollars?
Who's better for society? Does it really matter?
Lot's of questions before you can decide what's best. In most cases older workers are still supporting younger unemployed workers (someone is). Younger ERE are probably investing back into productive companies (but what are they doing?).
It's probably a fairly useless debate to consider which method is best. Down to an individual level, ERE is best for the person with no detriment to overall society. Besides why should it even matter in your decision? No one else seems to care beyond the individual level.
