Heh, it's been trending upward for centuries with lots of ups and downs though. For the last 3 decades it's been mostly upwards.
But now the trend might become different. I fear for the future of my kids in 30 years.
Your kids will live an even more luxurious life (perhaps not more fulfilling): be anywhere in the world in less than 3 hours, self driving electric cars, better healthcare services, and much more.
