Agreed; pretty much everything comes back to overpopulation.
We would already be going off planet if the space program had been in private hands instead of gov.

The cost of all that commuting -- in all respects, including pollution, national energy security etc -- must be counted as part of operating the factory. But that's hardly part of any corporate business plan today.
While I'm on the soap box....
We have a similar situation with houses. There is some progress with "green" construction, but it's a drop in the ocean. For a century, the concept has been to build a cheap house and keep it livable by pumping large amounts of energy into it continuously. While, if we build a house with enough insulation and thermal-mass, and heat-exchange ventilation, it won't take much more than body heat to keep the place warm.
Same in summer -- people have huge electric bills for air-conditioning -- on houses with black roofs, such as my former home in Sacramento, built in 1992. When I held my hand above my head I could feel heat radiating thru from the attic. No excuse. (I installed an attic ventilation fan, with corresponding inlets; it helped a good deal.)
