I think we're far away from our capacity in terms of hours per day, but not in terms of average output per day: being actively working much more ours a day would be mostly countered by the lowering of hourly productivity. Here's a Very Bad Analogy: even if you observe a sprinter runnning 100m in 10 seconds, you hopefully won't think "If only he wasn't slacking most of the day, he could run a marathon in 1h10"
