Many things are so much less efficient now, though.

Where formerly we ate what was in season, we now have produce shipped around the globe, sometimes raw foods shipped across the ocean and turned into process foods and then shipped right back again. We eat meat in nearly every meal.

We used to die quickly at home when we were incurably sick; now we cling to half-life for years or decades.

We used to let our kids out the front door when they were bored, now we drive them all over town for everything in their busy calendar.

When we wanted to learn how to do a job, we'd talk to someone doing it and start working directly under them, quickly making ourselves useful. Now we spend years learning totally unrelated stuff, just to prove that we're human beings with a pulse who can be hired.

Now, flying across the world to have fun is 'necessary,' because parks and natural areas in our own backyards are not enough.
