This is a tragedy of the commons. If the average adult height was shifted to about 4 and a half feet (1.37 meters) resource consumption in terms of food, transportation, building sizes, furniture and appliance sizes, clothing and linenry sizes, wash loads, heating and cooling (for smaller places) would all greatly decrease. We could have almost twice the number of people with the same resource expenditures. This would be a huge boon to the world and humanity. But, as you say, it pays to be taller than average (within limits). Just don't be involved in a roll-over accident in a standard sedan.
