If we could somehow give up all of the quality of life improvements of the past 70 years without giving up any of the productivity enhancements from the same timeframe, then sure, maybe everyone could work less. But, that doesnt make sense. Banking on my smartphone is more efficient than waiting in line for a teller, but it also means I need sufficient income to pay for the device and the network access (neither of which existed in 1950).
