Space is EXTREMELY difficult, dangerous, and demanding.
Private companies are in business to MAKE MONEY... PERIOD.
This means the emphasis will be AWAY from transporting HUMANS and in favor of commerce for the reasons listed above.
Now, shooting satellites into orbit is one thing private companies can do. But they WON'T spend a DIME on furthering Human Exploration into Space 'cause there's not much profit in it.
At least NOT UNTIL GOVERNMENT DEVELOPS THE TECHNOLOGY AND INFRASTRUCTURE TO MAKE IT SAFE AND PROFITABLE.
We as a Nation and Society have COMPLETELY forgotten what the Manned Spaceflight Program has done for our economy, technology, and education system.
And as someone who GREW UP just a FEW MILES FROM THE SPACE COAST, I can tell you the change initiated under nixon, accelerated under ray-gun, and finalized under bush II and Obama, is NOT in the long-term best interests of either our National Security OR our Society.
