Which fact do you dispute? That more Americans are employed today than at any other time in history? Or that Americans are wealthier today than at any time in history?
That is up to debate. There are more Americans now than any other time. We once only needed 1 parent to work in the economy to survive. Now alot of families have 2 bread winners. A Conservative view would like to have only one parent working while the other takes care of the kids.
Also, what do you mean by wealth? DVD's? We also have more debt than any other time. It is a interesting debate on our current economy as opposed to the past.
Inflation-adjusted GDP per capita.
We produce more per person (and therefore can consume more per person) than ever before in history.
